A Double-loop Control Structure for Tracking Control and Disturbance Attenuation

The development of high performance controllers capable of dealing with both tracking control and disturbance rejection has attracted considerable attention. This paper investigates the twodegree-of-freedom control structures with a disturbance observer and command feedforward control, respectively, and presents a double-loop control structure. The proposed control structure allows intuitive an...

A Double Closed-Loop Control Method for Quasi-Resonant Converter

To achieve the soft-switching condition and stabilize the output voltage of quasi-resonant converters, the paper proposes a double closed-loop control method (DCCM). In the inner loop, soft-switching is guaranteed with the off-time of the switch determined by the zero-crossing signal of the switching voltage. In the outer loop, the output voltage is regulated to be constant against load variati...

Equivalent Double - Loop Networks

Hwang and Xu defined equivalent double-loop networks and gave one such result showing that the L-shapes of the two equivalent networks are recombinations of three rectangles. Recently, Rödseth gave an elegant algebraic theorem for equivalent multi-loop networks. We show that its double-loop version yields equivalent networks of the 3rectangle version. We also show that other seemingly different...

Learning open-loop from closed-loop control

This paper explores an evolution from closed-loop control to open-loop control for a planar manipula-tor. A reinforcement learning strategy is used to learn the open-loop commands from the closed-loop control. The goal is to produce a motion using purely open-loop control strategy, thereby eliminating the need for inter-link communication and on-line control computations. Initially closed loop ...
