| Summary |
"Optimal design and analysis of a multivariable regulator may be achieved in either the frequency or time domain. This paper describes the formulation of the matrix Riccati equation in the time domain and the Wiener-Hopf equation and the root-square-locus in the frequency domain. The necessary requirements which must be satisfied in order to achieve an optimal control vector when using a quadratic performance index are presented for both domains. The resultant optimal control vector is shown to be a linear function of the system state vector. The effect of the quadratic performance index weighting matrices on the optimal system closed-loop poles, as well as the importance of picking "good" weighting matrices, is shown in this paper. A computer cost comparison of the two techniques of obtaining the optimal closed-loop roots indicates a marked advantage of the time domain approach over the frequency domain approach for high order systems"--Abstract, leaf ii. |
