This paper presents the PWM (Pulse Width Modulation) based speed control of three-phase asynchronous (Induction) motor. Induction motor is the leading machine used in many industrial controls, automation processes and in the field of HVAC applications. However, induction motor has fixed rated speed when directly connected to ac supply. It is necessary to design a drive system to obtain variable speed at its output to fulfill the application requirement. For this reason, we have designed a “VFD (Variable Frequency Drive)”, which gives desired speed- according to load changes unlike the DC motors, which do not require any speed controlling drive. Currently with the technological elevation in drive systems, the speed control of induction motor is more economical, convenient, reliable, and accurate. It provides continuous process control over a wide range of speed. VFD not only controls the speed of induction motor but also make its starting smooth by reducing starting inrush current and improves power factor. In result, power consumption is also reduced. In this paper, we have designed and analyzed the MATLAB/Simulink model of open loop drive system and then implemented an experimental hardware design.

Plc Program

This paper introduces a noval experimental teaching project. Different from previous experiment, in this project, three-phase motor can operate at multi-speed mode or continuously variable speed mode controlled by PLC and VFD. The obvious characteristic of the experiment is that the VFD is controlled by PLC automatically. The configuration of the experiment including hardware and software is introduced in detail. The results of the execuation of the PLC program reveals that three-phase motor can operate in two modes according to the instructions from PLC. In addition, the speed can be changed with the corresponding parameters seting. Therefore, the knowledge of PLC and VFD are combined in one teaching project, through which student can master more practical technique. The work of this paper is significant for improving the students’ comprehensive capability.

Variable Speed Control

Optimization techniques are increasingly used in research to improve the control of three-phase induction motor (TIM). Indirect field-oriented control (IFOC) scheme is employed to improve the efficiency and enhance the performance of variable speed control of TIM drives. The space vector pulse width modulation (SVPWM) technique is used for switching signals in a three-phase bridge inverter to minimize harmonics in the output signals of the inverter. In this paper, a novel scheme based on particle swarm optimization (PSO) algorithm is proposed to improve the variable speed control of IFOC in TIM. The PSO algorithm is used to search the best values of parameters of proportional-integral (PI) controller (proportional gain (kp) and integral gain (ki)) for each speed controller and voltage controller to improve the speed response for TIM. An optimal PI controller-based objective function is also used to tune and minimize the mean square error (MSE). Results of all tests verified the robustness of the PSO-PI controller for speed response in terms of damping capability, fast settling time, steady state error, and transient responses under different conditions of mechanical load and speed.

Induction motors are widely used from home to industrial applications. Speed of induction motor plays important role, so to control the speed of induction motor various techniques are adopted and one of these techniques is V/F control, which is adopted in this paper. This technique helps to control the speed in open control system in RPM. Moreover, Control is designed in LabVIEW, it is quite helpful to develop the circuit graphically and code is automatically written in the background to run on Field Programmable Gate Array (FPGA). The aim of this research is to study the impacts on diverse parameters during speed control of three phase induction machine with manipulation of GPIC. Solar technology is used as input source to drive the General-Purpose Inverter Controller (GPIC). Apart of this, impacts of modulation index and carrier frequency influencing the active, reactive and apparent power, temperature and power quality and current overshoot is analysed. MATLAB/Simulink and LabVIEW tools are used for simulation and results along with GPIC, Induction motor and solar panel as hardware.
