The robust H ∞ control problem for a class of uncertain switched linear systems by using the variable structure control is investigated. A robust H ∞ single sliding surface is shown to exist as long as a convex combination of the subsystems of the switched system is robustly stabilizable with disturbance attenuation level γ. A switching law is constructed via the single Lyapunov function technique. Variable structure controllers of subsystems are designed so as the resulting closed-loop system guarantees the robust H ∞ performance. An illustrative example and simulation results are given to demonstrate the effectiveness of the proposed design method.

In time delay control systems, the observed information is related to a past instant and using this delayed signal may cause unsatisfactory results in control system applications. This paper deals with how time delay information can be used in reorganizing the rule base so as to improve system performance. Basically, it proposes a new scheme of appropriate shifting of the rule base to compensate the information lag caused by time delay in the system. The parameters affecting the shifting scheme are discussed in detail and the shifting scheme is tabulated with respect to system model parameters. Applications of the new methodology in different systems are simulated and the effectiveness of the scheme is fully illustrated.
