The problem of designing a controller for a multi-vectored propeller airship with independent amplitude and rate saturations is addressed. First, a linear Proportional-Integral-Derivative (PID) controller is introduced for position control without considering the input saturations. Then, two design methods are applied to the traditional PID control output to satisfy the independent amplitude and rate constraints: the nested saturated PID controller (N-PID) and the transformed PID controller (T-PID). The bounded magnitudes and rate outputs of the modified controllers are given. Simulation results showed both controllers have good tracking performance while satisfying independent amplitude and rate saturations. However, the transformed PID controller has the advantage of expressing explicitly the relationship of the actuator magnitude and rate saturations with the parameters of the transformed function such that the actuator saturations are suppressed by calculation but not by trial and error.

This paper elucidates the modeling of a + quadrotor configuration aerial vehicle and the design of its attitude and altitude controllers. The aircraft model consists of four fixed pitch angle propeller, each driven by an electric DC motor. The hovering flight of the quadrotor is governed by the Newton-Euler formulation. The attitude and altitude controls of the aircraft were regulated using heuristically tuned (Proportional-Integral-Derivative) PID controller. It was numerically simulated via Simulink that a PID controller was sufficient to bring the aircraft to the required altitude whereas the attitude of the vehicle is adequately controlled by a PD controller.

Haptic devices had known as advanced technology with the goal is creating the experiences of touch by applying forces and motions to the operator based on force feedback. Especially in unmanned aerial vehicle (UAV) applications, the position of the end-effector Falcon haptic sets the velocity command for the UAV. And the operator can feel the experience vibration of the vehicle as to the acceleration or collision with other objects through a forces feedback to the haptic device. In some emergency cases, the haptic can report to the user the dangerous situation of the UAV by changing the position of the end-effector which is be obtained by changing the angle of the motor using the inverse kinematic equation. But this solution may not accurate due to the disturbance of the system. Therefore, we proposed a position controller for the haptic based on a discrete-time proportional integral derivative (PID) controller. A Novint Falcon haptic is used to demonstrate our proposal. From hardware parameters, a Jacobian matrix is calculated, which combines with the force output from the PID controller to make the torque for the motors of the haptic. The experiment was shown that the PID has high accuracy and a small error position.

Parameter Values

Pemanfaatan teknologi alternatif dalam bidang otomotif maupun otomasi industri menggunakan motor Brushless Direct Current (BLDC) sudah banyak digunakan karena memiliki kelebihan dibanding dengan jenis mesin penggerak bertenaga elektrik lainnya. Namun motor BLDC masih memiliki beberapa kekurangan ketika menerima beban sehingga menyebabkan penurunan kecepatan putaran pada motor BLDC. Tujuan penelitian ini adalah untuk merancang dan mengaplikasikan sistem kendali kecepatan motor BLDC dengan kontrol Proportional Integral Derivative (PID) dan menentukan nilai parameter untuk mendapatkan persentase error steady state terkecil pada variasi  kecepatan dan beban motor BLDC. Metode pengambilan data diambil dengan cara memasukkan nilai parameter secara trial and error. Sebagai simulasi beban, motor BLDC dihubungkan dengan generator yang diberi beban berupa lampu yang divariasikan. Hasil pengujian mendapatkan pemodelan blok diagram PID dengan Matlab Simulink. Hasil parameter kontrol PID diperoleh nilai Kp = 1,5; Ki = 10,5 dan Kd = 0,04. Dengan nilai parameter tersebut motor BLDC dapat mempertahankan nilai set point dengan kestabilan yang tinggi (error steady state rendah).   The usage of alternative technology in the field of automotive and industrial automation using Brushless Direct Current (BLDC) has been widely used because it has advantages compared to other types of electric-powered drive engines. But the BLDC motor still has some disadvantages when receiving a load that causes a decrease in rotation speed on the BLDC motor. The purpose of the study is to design and apply a BLDC motor speed control system with a Proportional Integral Derivative (PID) control and determine the parameter value to obtain the smallest error steady state percentage at a speed variation and motor load the BLDC. The method of retrieving data was taken by entering parameter values by trial and error. As a load simulation, the BLDC motor was connected to a generator that was given the load in the form of a varied lamp. The test results gets the PID block diagram modeling with Matlab Simulink. The results of the PID control parameter are Kp = 1.5; Ki = 10.5 and Kd = 0.04. With these parameter values, the BLDC motor can maintain the setpoint value with high stability (low steady-state error).

One learning lesson of PID control theory is to tune its proportional, integral, and derivative parameters so that the performance of system is optimal. Besides, teaching PID control theory verbally is challenging especially when transient response characteristics e.g. overshoot, rise time, and settling time are introduced. Thus, this study investigates the feasibility of a low cost mobile robot in conveying the knowledge of PID control theory. First, an inexpensive open-source mobile robot was modified so that the position of the robot can be recorded and visualized wirelessly. Second, a graphical user interface was built to visualize the movement of the robot. Lastly, the PID parameters were tuned and their effects were recorded and analyzed quantitatively. Findings show that the proposed method is capable of demonstrating the effects of P and D parameters correctly. </span>

Simulation Results

The classical proportional integral derivative (PID) controllers are still use in various applications in industry. Magnetic levitation (ML) systems are rigidly nonlinear and sometimes unstable systems. Due to inbuilt nonlinearities of ML systems, tracking of position of ML Systems is still difficult. For the tracking purpose of position, PID controller parameters are found by choosing Cuckoo Search Algorithm (CSA) of optimization. The ranges of parameters are customized by z-n method of parameters. Simulation results show the tracking of position of ML systems using conventional and optimized parameters obtained with the CSA based controller.

ABSTRAKVAWT (Vertical Axis Wind Turbine) tipe Darrieus NACA0015 merupakan salah satu model dari turbin angin yang bekerja dengan menggunakan angin sebagai sumber penggerak. Namun dari hasil pengamatan, kecepatan angin yang ada tidak konstan setiap saat. Sehingga dari permasalahan ini perlu suatu kontrol yaitu dengan mengendalikan sudut kerja blade VAWT yang dikenal dengan kontrol angle of attack (AoA). Prinsip kerja kontrol AoA yaitu sudut blade diatur agar VAWT bekerja secara optimum dan dapat meningkatkan efisiensi. Metode kontrol AoA menggunakan PID (Proportional–Integral–Derivative) dengan memberikan nilai trial and error pada Kp, Ki, Kd. VAWT ini menggunakan konstanta TSR (Tip Speed Ratio) yaitu 4. Hasil dari penelitian ini yaitu daya yang dihasilkan VAWT dengan kontrol AoA mendapatkan rata-rata efisiensi sebesar 5.16%, sedangkan VAWT tanpa kontrol mendapatkan efisiensi sebesar 3.49%. Sehingga dapat disimpulkan bahwa dengan kontrol AoA, rata-rata efisiensi dayanya naik sebesar 1.67% dari yang tanpa kontrol.Kata Kunci: Kontrol Angle of Attack (AoA), VAWT, TSR, Efisiensi ABSTRACTVAWT (Vertical Axis Wind Turbine) type Darrieus NACA0015 is one model of a wind turbine that works by using wind as a source of propulsion. Conditions from observations, wind speeds that are not constant every time. So from this problem needs control VAWT by controlling the working angle of the VAWT blade is the angle of attack control (AoA). The principle AoA control is that the blade angle adjusted so that the VAWT works optimally and can improve the efficiency. AoA control method uses PID (Proportional-Integral-Derivative) by providing trial and error values for Kp, Ki, Kd. VAWT uses TSR (Tip Speed Ratio) constant which is 4. The results of this research, VAWT with AoA control get an average efficiency of 5.16%, while without control gets an average efficiency of 3.49%. So it can be concluded that with AoA control, the average power efficiency increases by 1.67% from those without control.Keywords: Angle of Attack (AoA) Control, VAWT, TSR, Efficiency
