摘要: Summary The multivariable Nyquist array, and characteristic locus design techniques are evaluated by experimental application to the double effect, computer controlled, pilot plant evaporator at University of Alberta. These frequency domain procedures resulting controllers also compared with “optimal-quadratic” regulators, a conventional multiloop control scheme. All approaches were found produce better than scheme, best designed using ( output feedback ) favourably “optimal” state controllers. direct array technique is preferred authors but all give good insight into system performance and, from point view both designer operator, convenient, practical robust.
