Active Control of Suspension Systems based on H inf technique
نویسندگان
چکیده
There are many types of car suspensions control, H∞ control of vehicle suspension is studied in the literature for a brave time ago. We can define active suspensions as control systems incorporating a parallel spring and an electronically controlled damper. The contribution of this paper relies on H∞ control design to improve comfort and road holding of the car, and on control validation through simulation on an quarter Car and Half Car model with seat-passengers of the suspensions system. In this paper an H∞ controller is designed for a actuated active suspension system of a quartermodelled and half-modelled with seat-passengers vehicle in a cascade feedback structure, two H∞ controllers are designed for this system for two different model of suspensions. in this paper we will make a comparison between application of quarter car and half car model. Key-Words: Vibration Control, Active Control, Suspensions Control, Structure Dynamic.

متن کاملOptimal integrated passive/active design of the suspension system using iteration on the Lyapunov equations
In this paper, an iterative technique is proposed to solve linear integrated active/passive design problems. The optimality of active and passive parts leads to the nonlinear algebraic Riccati equation due to the active parameters and some associated additional Lyapunov equations due to the passive parameters. Rather than the solution of the nonlinear algebraic Riccati equation, it is proposed ...
