Figure 1: Quarter-car model of active suspension.
Control Architecture
The quarter-car model is implemented using Simscape Multibody. The following Simulink
model contains the quarter-car model with active suspension, controller and actuator
dynamics. Its inputs are road disturbance and the force for the active suspension. Its
outputs are the suspension deflection and body acceleration. The controller uses these
measurements to send control signal to the actuator which creates the force for active
suspension.

Control Objectives
Our goal is to achieve three control objectives:
- Good handling defined from road disturbance to suspension deflection.
Tuning for Multiple Values of Plant Parameters
