This paper presents a new approach on the plant augmentation and target feedback loop parameterization for the discrete-time LQG/LTR control. With the proposed procedure, the bound on the sensitivity of the control loop can be associated with the behavior of the inverse of any real stable pole, ensuring good properties of disturbance rejection and tracking of reference signals in situations where...
Repetitive control (RC) is a widely used effective approach for periodic reference tracking and periodic disturbance rejection. In this paper, its use for periodic disturbance rejection and piecewise constant reference tracking is analyzed in a continuous-time framework. First, two previously proposed repetitive control structures, namely the basic repetitive controller and the current iteration repetitive...
A robust fuzzy control design based on gain and phase margins specifications for nonlinear systems, with time delay, via multiobjective genetic algorithm, in the continuous time domain, is proposed. A Fuzzy C-Means (FCM) clustering algorithm estimates the antecedent parameters and the rule number of a Takagi-Sugeno fuzzy model, through from input and output data of the process, whereas the least squares...
Presented herein is Uniform Time Division (UTD) of Maximum Power Tracking for Distributed-Input Parallel-Output (DIPO) converter power systems. The primary objective of UTD for DIPO converters is to periodically spend equal time in processing maximum power from each of distributed sources using only one MPT non-linear controller. As a result, the UTD-MPT controller sequentially provides equal time...
