In this paper, an overview of recent advances in digital control of low- to medium-power dc/dc switching converters is presented. Traditionally, such dc/dc converters have been almost exclusively controlled through analog electronics methods. However, with the steadily decreasing cost of ICs, the feasibility of digitally controlled dc/dc switching converters has increased significantly. This paper...
The synthesis control of force and position in electro-hydraulic servo system has been applied to some special occasions. Analyzed a typical system which adopted this kind of control algorithm. Applying unchanged structure theory, the compensated transfer function has been deduced, the compensated state-space model is presented. Considering the synthesis control should meet the requirement to force...
This paper introduces a innovated representation model, namely, a discrete-time switched fuzzy system, which differs from existing ones. In this model, a system is a switched system whose subsystems are all discrete-time T-S fuzzy systems. Using switching technique, the single Lyapunov function method and multiple Lyapunov functions method, the state feedback controllers are built to ensure that the...
A double forward multiple output converter with weighted time-sharing control and switch-linear hybrid (WTSC-SLH) technique is presented in this paper. Total regulation of both output voltages is obtained by WTSC. Precise regulation and low ripple multiple output voltage can be achieved by a post regulator with SLH approach. The effects of WTSC-SLH is verified on an experimental two-output double...
