SIMULATION ANALYSIS OF HYDRAULIC ACTIVE SUSPENSION BASED ON LQG THEORY

Abstract

Abstract: A single-wheel mathematical model of hydraulic active suspension system composed of servo directional valve is set up. After the optimum control problem is transferred to standard LQG problem, simulation is performed to show that the hydraulic servo system, within several restrictions, can produce a satisfactory effect on vibration control. The all - state feedback control and output feedback control are also discussed.

Key words: Active control, Hydraulic servo system, LQG problem, Stochastic control
