Linearly Combined Suboptimal Mixed H 2 =h 1 Controllers

In this paper we propose some new solutions to the full information mixed H 2 =H 1 state feedback problem: the H 2 norm of the closed-loop system is minimized over a class of linearly combined state feedback laws that satisfy the speciied H 1 bound. Such mixed linearly combined controllers yield smaller closed-loop H 2 norms than those obtained by using the central solutions of the H 1 problem....

Design of Optimal Mixed H 2 / H m Static State Feedback Controllers

Despite the recent advances in robust control theory, the robust performance problem formulated in the mixed H2/Hm framework largely remains an open problem. In this approach, one seeks a controller that minimizes the Hz norm of a closed-loop map over all admissible controllers while satisfying an H , constraint on another closed-loop map. Unlike the optimal H Z problem or the y-level sub-optim...

Mixed H 2 = H 1 control : Synthesis equations for the discrete - time case

A discrete mixed H2/H1 optimal control problem is studied, where an upper bound on an H2 cost is minimized subject to an H1 norm bound on the closed-loop transfer function. New synthesis equations for the optimal controller are obtained, which are the discrete-time counterparts of continuoustime synthesis equations given in the literature. The synthesis equations are obtained by deriving a set ...

Active Suspension vibration control using Linear H-Infinity and optimal control

In this paper, the 1/4 vehicle model have been simulated. The vehicle body acceleration using optimal control has been optimized. The vehicle ride comfort is achieved by using robust control, and it has been compared with optimal control. The active suspension can help the vehicle to have a good dynamic behavioral. In this paper, two degrees of freedom dynamic vibration model of a general ve...
