State Based Functional Observer Design for Linear Uncertain Systems Using Multirate Output Sampling

Abstract

In this paper a design of controller has been proposed for linear uncertain systems based on multirate output sampling for the purpose of state feedback and nullification of disturbance effect on system response. If certain conditions are satisfied, construction of proposed functional type controller require less number of output samples than any other method based on fast output sampling. The advantage of proposed method is that it can be extended to unobservable systems and avoids the boundedness constraint on disturbance. A numerical exam- ple demonstrates the procedure, superiority in terms number of required output samplings and application to unobservable systems.
