Abstract: This hybrid motorcycle design is to combine 5.65kW gasoline engine and 48V DC 0.5kW electrical brushless motor in serial-parallel type. Master control unit use a microcontroller ATMega16 to control gasoline engine and electrical motor alternately. Speed sensor is placed on the rear wheel to detect the motorcycle’s speed. When the motorcycle’s speed reaches the top threshold at 30km/h, it driven with gasoline engine and when the motorcycle’s speed getting lower to the bottom threshold at 5km/h, it changes with electrical motor. Battery charged with plug-in system to power supply.

There will be the pantograph-catenary arc (PCA) when the pantograph of a high-speed train is separated from the power supply line, and the electromagnetic interference (EMI) caused by the PCA can affect speed sensors of the train. To study the influence of the PCA, firstly, the traction control unit (TCU) speed sensor of the high-speed train is researched. The result shows both overvoltage and electromagnetic radiation (EMR) generated by the PCA can influence the signal of speed sensor. Secondly, the composite model of the train is established. Then, the interference of the PCA on the TCU speed sensor is verified. The results of practical measurements show the PCA causes a maximum overvoltage of 680 V on train body (TB) and increases the magnetic field around TB to a maximum of 58 dBµA/m. This is the reason of sensor malfunction, which is consistent with the theoretical and simulation results. Finally, the methods to reduce the EMI of the PCA are proposed.

The article introduces the design of the half-bridge switching and regulated power supply system which is based on PWM. The design mainly consists of regulated power supply’s structure of basic hardware circuit, its working principles and the process of modeling simulation and software design. The control circuit controls SG3525 chip to output PWM wave through the Microprocessor Control Unit (MCU) of AT89C51 and drives IGBT through the chip of EXB841 as well. The MCU is also used to realize the keyboard process and controls of the pulse width and frequency. Taking advantage of Simulink (dynamic simulation Toolbox) and SimPowerSysterm (power simulation Toolbox) of MATLAB, it simulates the designed regulated power supply. According to the simulation result of this design, the system has high stability and good output waveform. The operation of the design is simple and clear with less software operation and higher speed.

With progress in internal combustion engine fuel economy, variable cylinder systems have attracted attention. We measured fuel consumption in cylinder cutoff by stopping the injector alone, collected data changing the location and number of cutoff cylinders and when varying the cutoff cylinder, and compared the difference in fuel cost reduction. A transistor is inserted serially into the injector control circuit of the electronic control unit (ECU). By controlling the transistor via microcomputer, the injector is turned on or off independently from ECU control in obtain cylinder cutoff. The amount of fuel consumption is measured using enhancement mode of a failure diagnostic device based on the OBD II standard to collect injection time and rotational speed of the injector for a predetermined time and calculated based on this data. We confirmed that by stopping the injector alone, fuel consumption was reduced 6 to 22% and is reduced when the cutoff cylinder is varied.

This paper presents model-based design and hardware-in-the-loop (HIL) simulation of engine lean operation. The functionalities of the homogeneous combustion subsystem in engine Electronic Control Unit (ECU) in dSPACE Automotive Simulation Models (ASM) are first analyzed. To control the gasoline engine in lean operation without the drop of output torque, the combustion subsystem in engine ECU is modified by introducing two control loops, torque modifier and fuel multiplier. The performance of these two controllers is evaluated by HIL simulation using a dSPACE HIL simulator. The HIL simulation models, including vehicle plant model and softECUs in HIL simulator and engine lean control model in hardware engine ECU are modeled using model-based design. With HIL simulation, the designed engine control strategies can be immediately tested to evaluate the overall vehicle performance. The HIL simulation results show that the designed lean combustion control strategy can reduce fuel consumption and is able to meet the torque requirement at lean engine operating conditions.

Dust is a very small solid particle (generally in units of micron) carried by air so it can be breathed anywhere either outdoors or indoors. According to the decision of kepala badan pengendalian dampak lingkungan number: Kep-107/Kabapedal/11/1997, dust exposure is one of the indicators of air pollution affecting the quality of life and public health. Therefore, a system capable of detecting and controlling the level of dust exposure is required. In this study a dust-proof detection was designed using the GP2Y1010AUOF sensor as a dust or particulate matter (PM10) and DS18B20 sensor which is a digital temperature sensor to monitor room temperature. As a simulation of air neutralization used mini car home dual use usb humidifier water-drop air purifier aroma diffus, Arduino Uno as Master Control Unit (MCU) which functions to manage data sensor readings into digital data and to display the level of exposure of dust and air temperature of the room is used LCD character 16x2. A graphical and numerical display of data is displayed on a computer or laptop using graphical user interface LabVIEW.

This paper presents the data of comparative studies of the characteristics of the Mxus XF15R brushless elec-tric motor (rotation speed; consumed current, power and efficiency) depending on the maximum torque. The de-sign of the stand for studying the characteristics of the seeding process when using an electric drive of the seed-ing disc is presented; the key elements of the stand are: the seeding section, seeding disc, electric motor connect-ed to the seeding disc, the control unit, the source of rare-fied pressure, the seeding disc speed sensor and the seeding sensor. The technique of working with the stand and the procedure for setting it up are described. During the operation, the following indicators are taken into ac-count: control signal of the seeding disc drive; seeding disc and rotor revolutions, rpm; the number of the seed in the total volume from the moment of measurement; time between seeds falling, ms; vacuum, kPa; hole diameter, mm; reference time between the fall of adjacent seeds at a given rotational speed of the seeding disc, ms. During the experiment, it was found that with a value in the seed-ing chamber of 5 kPa, in the frequency range of the seed-ing disc from 17-100 rpm, the actual seeding rate was 3.28 pcs m, the number of twins in the seeding process was 8.17%, the number of gaps in the sowing process was 5.46%, and the deviation from the set rate was 5.2%. Thus, the electric drive of the seeding disc based on the brushless DC motor XF15R Mxus has shown its efficiency and may be used in the existing configuration of the MC type sowing device.

The main objective of this paper was to conceive a new electronic control circuit to the throttle device. The throttle mechanical actuator is the most important part in an automotive gasoline engine. Among the different control strategies recently reported, an easy to implement control scheme is an open research topic in the analog electronic engineering field. Hence, we propose using the nonlinear dwell switching control theory for an analog electronic control unit, to manipulate an automotive throttle plate. Due to the switching mechanism commuting between a stable and an unstable controllers, the resultant closed-loop system is robust enough to the control objective. This fact is experimentally evidenced. The proposed electronic controller uses operational amplifiers along with an Arduino unit. This unit is just employed to generate the related switching signal that can be replaced by using, for instance, the timer IC555. Thus, this study is a contribution on design and realization of an electronic control circuit to the throttle device.
