This paper presents a phase-locking-loop-based (PLL-based) charge control scheme to enhance the cross regulation (CR) performance of charge-controlled SIMO Buck DC-DC without freewheel period. By combining PLL structure with traditional scheme, each channel could be regulated by an independent loop. Moreover, gain-adapted pump (GACP) technique is applied for stability in multi-load condition. T...

The problem of output regulation for nonlinear control systems with guaranteed transient performances in the presence of uncertainties is discussed, where the nonlinear systems are nonaffine in the control. The fast dynamical controller with the highest output derivative in feedback loop is used, where the controller is proper and can be implemented without ideal differentiation. Two-time-scale...

Multivariable plants under input constraints such as actuator saturation are liable to performance deterioration due to problems of control windup and directional change in control action. In this paper, we propose a two-stage internal model control (IMC) antiwindup design which guarantees optimal closed loop performance both at transient and at steady state. The two-stage IMC is based on the s...

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 ...

C. R. Fuerte-Esquivel Universidad Michoacana de San Nicolás de Hidalgo, Morelia, Mexico Abstract A general approach to real-time transient stability control is described, yielding various complementary techniques: pure preventive, open-loop emergency, and closed-loop emergency controls. Recent progress in terms of a global transient stability-constrained optimal power flow is presented, yieldin...

These models are suitable for analysis in the time domain, which is especially useful for load transient simulations. Linear models that can be transformed to the frequency domain for analysis are derived from the Hamiltonian models. The duty cycle is included in the input signal vector, enabling full system analysis with respect to the system’s transfer functions: audio susceptibility, output ...

Abstract. A new multi-loop controlled low dropout (LDO) regulator featuring with improved transient response and low quiescent current is presented in this paper. The proposed Multi-Loop Control (MLC) technique adopting both feed-back and feed-forward control methods to realizes the fast response ability by regulating the load current and output voltage through separate loops rapidly. In additi...
