摘要:

We derive the parametrization of all controllers that achieve both the robust-tracking and the deadbeat control. We also give the parametrization of all reference functions for which the robust tracking and designed deadbeat property is guaranteed by all robust-tracking deadbeat controllers for one reference. The solution to the robust-tracking deadbeat problem for more than two reference functions is also given. We use theH∞-norm of the sensitivity function as the robustness index of the system. By using two-degree-of-freedom control systems, we can achieve both minimal-time deadbeat control and optimal robustness with only one controller.

摘要:

State space algorithms are developed for the optimal three-degree-of-freedom Wiener-Hopf controller without placing any restriction on the plant. The algorithms are obtained not only for the regulator problem but for the servo problem as well and with or without feedforward control.

摘要:

In this paper we present a solution to the ‘standard’ ℋ2control problem. The solution presented here is based upon the algebra of polynomials, and in particular we use thepolynomial equation approach. In considering the scalar version of the standard ℋ2problem we derive a couple of linear polynomial (diophantine) equations which define the optimal regulator. The coefficients of these equations are obtained from polynomial spectral factorization.

摘要:

This note presents a stability result for the multivariable version of the Generalized Predictive Control algorithm (Shahet al. 1989). In particular, closed-loop stability is obtained for any open-loop asymptotically stable plant by a proper selection of the future output horizon and of the control weighting matrix. The control law contains an integral action, thus guaranteeing regulation with zero steady-state error for constant exogeneous signals.
