Nonlinear Ride Height Control of Active Air Suspension System with Output Constraints and Time-Varying Disturbances

This paper addresses the problem of nonlinear height tracking control of an automobile active air suspension with the output state constraints and time-varying disturbances. The proposed control strategy guarantees that the ride height stays within a predefined range, and converges closely to an arb...
