โœฆ Synopsis

A systematic procedure is proposed for the design of multivariable feedback control systems. For an N x N multivariable control system, the desirable overall compensator is decomposed into N cascaded sub-compensators to be determined in each step. The stabilityequation method is used to find the desirable sub-compensators. After step N, the overall closed-loop system can be designed diagonal dominant and have a desirable performance closely related to the characteristic roots of each subsystem. A 4 x 4 boiler furnace system is chosen as an example, and comparisons are made with methods in the current literature.

This paper presents a new method to convert a characteristic equation from the z-domain to the w-domain, which is best suitable for the stability-equation method. Stability criteria applicable to sampled-data control systems with characteristic equations having both real and complex coefj?cients are

The linearized model&g of a synchronous generator with exciter, along with a powerful model order-reduction method and two eficient pole-placing algebraic control methods (i.e. the spectral and control-canonical-form (CCF) using state and/or output feedback) have been presented in systematic and con
