STATIC OUTPUT FEEDBACK CONTROLLERS FOR CONTINUOUS-TIME SYSTEMS WITH INPUT-OUTPUT NONLINEARITIES

摘要

In this paper we develop a static output feedback controller synthesis framework for continuous-time multivariable linear time-invariant systems subject to input-output time-varying nonlinearities. The proposed framework directly accounts for robust stability and robust performance over the class of input-output nonlinearities. Specifically, using absolute stability theory we develop a controller synthesis framework for constructing feedback controllers with a guaranteed domain of attraction for systems with input nonlinearities. The proposed design approach provides a systematic procedure for loop shaping and hence can account for classical design objectives within a modern multivariable control-system design framework.
