Comparison of three control methods for active engine mount

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.
