Abstract:In order to meet the ride comfort of the vehicle, a PID control strategy was proposed for the semi-active control of a 6 degree-of-freedom half-car suspension system model with a magnetorheological (MR) damper. Using the preferable solvability of the iterative linear matrix inequality (ILMI) algorithm, the parameters of the PID controller were obtained by the ILMI algorithm. Numerical examples demonstrate that with a proper control strategy semi-active suspension with MR damper can improve both the ride comfort and driving safety.
Keywords:semi-active suspension  magnetorheological (MR) damper  PID control  iterative linear matrix inequality (ILMI)
