Improved single neuron PID control for heavy-duty vehicle magnetorheological seat suspension

A semi-active seat suspension scheme is presented to replace the passive damper of traditional seat suspension. A human body-seat five-DOF model is applied to this system which includes a modified Bouc-Wen model for MR damper. An improved single neuron PID controller is proposed to enhance the seat suspension dynamic performance. A simulation model was established with MATLAB/SIMULINK and the simulation results indicate that this controller can effectively improve the antivibration effect of the seat, absorb the shock on driver, and improve enhance the riding comfortableness.
