For the active suspension control system, selecting sprung mass velocity and suspension deflection as controller inputs and active force as controller output, this paper considers a multivariable PID controller design problem with pole configuration and H ∞ performance constraints. Transforming the PID control problem into a static output feedback control problem and using the coordinate transformation matrix optimization method, this paper develops an algorithm to design the parameters of the multivariable PID controller. Finally, MATLAB/Simulink is used to analyze the performance of this controller. Simulation results show that the multivariableH ∞ PID active suspension controller obtained by this design algorithm significantly enhances the vehicle ride comfort, while ensuring good handling stability and meeting the mechanical constraints of suspension.
