DYNAMIC FEEDFORWARD OUTPUT-FEEDBACK CONTROL OF NONLINEAR PROCESSES

This paper addresses the feedforward/output feedback control problem f or single-input single-output minimum-phase nonlinear processes. Combi nation of dynamic feedforward/static state feedback laws and state obs ervers is employed to synthesize nonlinear dynamic feedforward/output feedback controllers that completely eliminate the effect of measurabl e disturbances and induce a desired input/output behavior. The develop ed methodology in applied to an exothermic continuous chemical reactor and extensive simulations illustrate the controller performance and r obustness.
