Abstract
In this paper, a recently proposed novel vehicle suspension of Parallel Active Link Suspension (PALS) is adapted on a quarter car test rig. Control strategies with the PALS are studied and synthesized for ride comfort and road holding performance enhancement. A linear equivalent model of the PALS-retrofitted quarter car is derived, with geometric nonlinearity compensated. A linear control scheme is then synthesized, with an outer-loop H-infinity control and an inner-loop actuator torque tracking. Nonlinear simulations with the model of the PALS-retrofitted quarter car test rig are performed over typical road profiles, including 2 Hz harmonic road, smoothed bump and hole, and ISO random road. Results are discussed to evaluate the potential of the PALS-retrofitted quarter car test rig in ride comfort and road holding performance enhancement, as well as the power consumption in the actuator.
