Wiener-Hopf design of optimal decoupling one-degree-of-freedom controllers

摘要: This reasonably self-contained paper is directed to the design of a multivariable optimal one-degree-of-freedom feedback loop which incorporates decoupling controller in forward path. The criterion for optimality quadratic-cost functional that penalizes both tracking error and saturation. controllers on optimization based are general enough allow non-unity rectangular plant transfer matrices possessing normal row rank. Nevertheless, sake brevity clarity, attention focused mainly square case. Earlier treatments problem have employed multi-degree-of-freedom controllers. solution we present case considerably more difficult obtain, especially when saturation taken into account. Explicit formulas derived set all yielding finite cost, as well those optimal. It shown these strictly-proper under conditions usually prevailin...
