An attempt, herein, is made to present a comprehensive solution of Jerk vs. ForceOptimal-Control of active suspensions. The comparison is made for a 1/4 car model; however, the body acceleration and jerk are directly from the system Hamiltonian. Also, in both J.O.C. and F.O.c. solutions, the force actuator is used to implement the controller. The results show that a reduction of jerk and acceleration is obtained against a higher rattle space and tire deflection. The compromise/tradeoff can be managed by setting appropriate weights in the cost function.
