The design of controllers for the multivariable robust servomechanism problem using parameter optimization methods

摘要: The problem of designing realistic multivariable controllers to solve the servomechanism is considered in this paper. Specifically it desired find a controller for plant robust problem, so that closed loop stability and asymptotic regulation occur, also other desirable properties controlled system, such as fast response, low-interaction, integrity, tolerance variations, etc. occur. method design based on using state space methods via two-state process: (1) theory, determine existence solution control structure required (2) nonlinear progranming methods, unknown parameters minimize performance index system subject certain constraint requirements. Numerous examples, varying from single-input/single-output four-input/four-output are given illustrate method, results obtained compared with by alternate methods. In all cases, have been highly competitive (i.e. always superior)
