This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller.  Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...

In this paper, a minimum entropy control approach for closed-loop tracking error is studied for linear dynamic control systems subjected to stochastic disturbances. The basic idea is to construct a feedback control scheme with the guaranteed closed loop stability using the Youla parameterization that provides a set of free parameters embedded in the controller. The entropy of the closed loop tr...

The study and the determination of polyhedral regions of local stability for linear systems subject to control saturation is addressed. The analysis of the nonlinear behavior of the closed-loop saturated system is made by dividing the state space in regions of saturation. Inside each of these regions, the system evolution can be represented by a linear system with an additive disturbance. From ...

This paper discusses robust sampled-data control for uncertain systems with time-varying delay. We allow a time-varying sampling. When we use digital devices to control systems, we usually apply the zero-order control input. In this case, the closed-loop system with such a state feedback control input becomes a system with time-varying delays in state. We first give a sufficient condition for t...

We consider the control design for a class of single-input single-output (SISO) switched linear systems of arbitrary order. Our approach is motivated by applications in which the major design objective is to achieve similar behaviour of the closed-loop system in each system mode ensuring stability for arbitrary switching. We study the stability of the resulting closed-loop system and exploit th...

This paper presents a feedback-controlled, MEMS-fabricated microaccelerometer. The microaccelerometer has received much commercial attraction, but its performance is generally limited. To improve the open-loop performance, a feedback controller is designed and experimentally evaluated. The feedback controller is applied to the x/y-axis microaccelerometer fabricated by sacrificial bulk micromach...

Abstrad-Two different predictive control formulations are developed based on minimization of the worst-case quadratic cost for systems with bounded parameters. The two formulations differ on the assumptions made about the future inputs in optimizing the current input: one assumes open-mop control, while the other considers closed-loop control. Their closed-loop properties such as asymptotic sta...
