摘要
应用LMS自适应前馈控制、LQR控制和模糊PID控制3种方法对发动机电磁式主动悬置进行研究。在MATLAB/Simulink环境下建立了主动悬置控制系统模型,并以车身垂向加速度为性能指标进行了仿真分析,对比了采用上述3种控制方法时主动悬置的隔振能力、鲁棒性和稳定性。仿真结果表明,在主动悬置的控制上模糊PID控制方法优于其他两种控制方法。
LMS adaptive feedforward control,LQR control and fuzzy PID control three methods are applied to the study on the control over active engine mount with electromagnetic-actuator.A model for active engine mount control is set up in MATLAB/Simulink environment,and a simulation is conducted with vertical acceleration of car body as performance indicator,in which the vibration isolation capability,robustness and stability of active engine mount with above-mentioned three control methods are compared.The results of simulation indicate that fuzzy PID control is superior to two other control methods in active engine mount control.
