Four-Stage Continuous-Time Feedback Controller Design
In this chapter, the results of three-stage continuous-time feedback controller design from Chap. 4 are extended to the four-stage feedback controller design. This facilitates independent control of four subsets of system state variables representing four artificial or natural subsystems of a system under consideration. The newly derived technique requires only solutions of reduced-order subsystem level algebraic equations for the design of appropriate local feedback controllers using only the corresponding subsystem state feedback (partial feedback). The local feedback controllers are combined to form a global controller for the system under consideration. The technique presented facilitates designs of independent full-state feedback controllers at the subsystem levels. Different types of local controllers, for example, eigenvalue assignment, robust, optimal in some sense, and observer-based controllers, may be used to control different subsystems. This feature has not been available for any other known linear feedback controller design technique.
