摘　　要：针对车辆液压自发电系统中存在的参数时变性、死区非线性等问题,提出利用模糊自整定PID控制器对整个系统控制。通过对PID参数在线自调整,改善系统的动态性能。利用MATLAB对系统进行建模与仿真,仿真结果表明:模糊自整定PID控制器能够明显改善由于负载扰动带来的稳态误差,改善被控过程的稳态和动态性能,提高系统控制精度和抗干扰能力,使整个系统具有较强的鲁棒性。To solve the problems such as time-variable parameters, nonlinear dead zone of the hydraulic self-generating system in vehicle, a fuzzy self-tuning PID controller was proposed to control the whole system. Through on-line adjusting PID parameters, the system dynamic response performance was improved. Modeling and simulation of the system were made using MATLAB. The simulation results demonstrate that the fuzzy self-tuning PID controller can obviously improve the steady-stAte error brought by load disturbance, improve the stability and dynamic characteristics of the controlled process, increase system control precision and anti-disturbance ability, enable the overall system have strong robustness.
