Real-Time Optimization of Automatic Control Systems With Application to BLDC Motor Test Rig
TLDR
The proposed approach is an alternative realization of Youla parameterization which allows the performance of the controlled systems to be improved without modifying or replacing the predesigned control systems, while the closed-loop stability is guaranteed.Abstract:
Driven by the increasing demands on production quality, system performance, and the reliability and safety issues of process industry, this paper proposes an integrated process monitoring and control design technique for industrial control systems. The proposed approach is an alternative realization of Youla parameterization which allows the performance of the controlled systems to be improved without modifying or replacing the predesigned control systems, while the closed-loop stability is guaranteed. In addition, a residual signal is available for the fault detection and isolation purpose. The effectiveness and performance of the proposed approach are demonstrated on a brushless direct current motor test rig.read more

Canonical forms for linear multivariable systems
TL;DR: In this article, a class of well-known canonical forms for single-input or single-output controllable and observable systems are extended to multivariable systems, and it is shown that, unlike the single variable case, the canonical forms are generally not unique, but that the structure of the canonical form can be controlled to some extent by the designer.
