Abstract : This paper presents iterative schemes and continuation schemes for designing robust controllers which stabilize dynamic systems having bounded parametric uncertainties. Utilizing results of the cheap control problem, some existence conditions of the robust controller are obtained, which are different from the matching conditions. Continuation schemes are used to overcome the divergence problem of iterative schemes. The robust controller design method is extended to nonlinear system and easily implementable series solution is also obtained. Results are illustrated with simple examples.
