Abstract :
A synthesis procedure for a H/sub /spl infin// precompensator and a H/sub /spl infin// dual postcompensator is proposed. Linear time invariant (LTI) systems are considered. Explicit formulas for the stabilizing precompensator and dual postcompensator are proposed. Sufficient stability conditions are given for the overall system. A LTI robust precompensator and dual postcompensator are designed for the nominal plant solving the mixed sensitivity problem. The overall system is implemented by output feedback. A simulation example for a MIMO system is given.
