STUDIES OF MULTIVARIABLE ROOT LOCUS DESIGN

Abstract

spite the considerable progress made in automatic control during recent dosda s at both theoretical and prao- tioei le lei aM although the sub eat ia now reaching maturity, the control of anilttvonieblo systems s those with several inputs and outputc) is still not well developed or widely known. This in fact, although wderstan4sble, constitutes a serious deftatency, sire the control of ootplex Industrial processes, of an 'eseóntially multi.' variable nature, is now opening up a vast tlold of applie.- ati en for the Control Brzgineers. The root locus approximation p oedure is extended to provide for the eomplex.'plane analysis of ovations?,i wbicb contain a term quad at c in the variable parameter in addition to the usual tee. In this dissertation, an attempt is mde to the design of linear time invariant mul' vsri*ble feedback systems. Zn particular some examples are attempted to draw root IOOU$
