Based on the H∞ control theorem,by introducing the H∞ performance index,a novel roubst adaptive observer using Lyapunov approach is designed for a class of MIMO linear time-varying systems with parameter uncertainties.

The feasibility is evaluated by numerical simulation and the results demonstrate that the proposed controllers can guarantee that the resulting closed-loop systems are quadratic stable and have desired H∞ performance index in each operating region.

The dynamic decoupling control was adopted, and for the parameter sensitivity disadvantage of dynamic decoupling, the variable structure robust compensating control was proposed to attenuate the remaining coupling to a suitable level, and achieve an H ∞ tracking performance index.
