Abstract
This paper illustrates the use of nonlinear control theory for designi ng electro-hydraulic active suspensions. A nonlinear, ''sliding'' cont rol law is developed and compared with the linear control of a quarter -car active suspension system acting under the effects of coulomb fric tion. A comparison will also be made with a passive quarter-car suspen sion system. Simulation and experimental results show that nonlinear c ontrol performs better than PID control and improves the ride quality compared to a passive suspension.
