Abstract: With Bosch company DV - E5 type throttle as control object，the hardware and software of the control system has been designed based on PID control algorithm. System uses TT89C51 microcontroller as the main control unit, using LMD18200 chip to drive DC motor in the throttle, at the same time, using PCF8591 as the AD conversion chip, using LCD1602 to display the dynamic control parameters. The system control software has been written by C language, The main software modules have been simulated on Proteus, an PID control experimental platform of the electronic throttle has been built, Test and the experiments of the opening degree position control on the throttle have been completed, the experimental results show that the system step response time is about 300ms, the steady-state error is less than 1%, hysteresis and overshoot is not obvious.

Control theory has been constantly enriched and control functions developed from single integrated. With the development of domestic research, some car manufacturing companies and university research institutions have obtained certain results. Articles in control theory focus on the theory of PID control, fuzzy control theory, sliding mode variable structure control theory research and more mature theory, and then, the above theories were compared.

Abstract: The electronic throttle promotes the development of electronically controlled vehicle systems. The emergence of electronic throttle technology is in the United States in the 1980s.After that it is developed in Europe and Japan. As the technology advances and the cost reductions, the electronic throttle has been widely used in modern cars. China's electronic throttle technology comes from the introduction of technology, the core technology, however, still do not grasp. With the continuous progress of the domestic automobile manufacturers and domestic universities, electronic throttle has been applied in various models. In hybrid vehicles, the continuously variable transmission vehicles, the natural gas engines, diesel engines, and motorcycles，the electronic throttle is applied in research and obtain the corresponding scientific research. In the future of the car electric system, the electronic throttle will play an increasingly critical role and obtain the wide range of applications.

Abstract: Due to some nonlinear factors and time delay in electronic throttle, the opening of electronic throttle is difficult to control. For overcoming these difficulties, in this paper a fuzzy adaptive PID controller is designed for an electronic throttle control system. The model of electronic throttle control system is built based on Matlab/Simulink and realized with a hardware-in-the-loop simulation system, which is based on MACS565. Simulation research and experiment results show that, compared with PID control system, the fuzzy adaptive PID control system, has some advantages. The all performance index with the fuzzy adaptive PID control is better than that of the PID control.

Abstract: A new approach is presented in this paper in which a Crush Natural Gas (CNG) Turbo Engine model based on Mean Value Model and transient dynamics are included. The model could simulate engine speed, torque, dynamic load, electronic throttle, turbo, temperature and emission conditions. The model was downloaded and run in a HIL platform joint with Labview and a CNG engine ECU. Simulation results indicate that it acquires good balance between Real-time response and dynamic accuracy, besides good comprehensive running status parameters including dynamic, mechanic, thermo and combustion. The model made it possible for electronic engineers to begin their works earlier to find solutions for power loss, high working temperature of CNG engine with more flexibility and lower bench test expense.

Abstract: Electronic throttle is a typical nonlinear device because of the nonlinear reset springs. Normal sliding mode control usually leads to chattering. To reduce chatters, a sliding mode control method based on compensation of nonlinearity is proposed, in which an observer is designed to observe and compensate the nonlinearity. A Lyapunov function was constructed to prove that control system is stable. Simulation and experiment results indicate that the proposed method can reduce chatters and achieve good control robustness.

Abstract: This paper introduces the structure and working principles of the automotive electronic throttle control system. After analyzing the non-linear factor of the system, mathematical model of the system is built up. And the working principle of non-linear torque observer is described. Then incremental PID controller and non-linear torque compensator were designed and simulated in the matlab/simulink. From the result, we can see that the control precision of incremental PID controller is poor, and it also easily has an overshoot. However, PID controller based on non-linear torque observer has a better tracking performance. It can meet control requirements very well.
