in this paper, we investigate the parameters affecting total harmonic distortion (thd) and power supply rejection ratio (psrr) in pwm class d amplifiers (cdas) on the basis of linear models with feedback. from our mathematical analysis, we show that the thd of a pwm class d amplifier with feedback can be improved by increasing the gain of the integrator through adding another amplifier at the o...

This chapter describes a new framework for the design of a novel suboptimal statefeedback-sliding mode control for output tracking while H2=H∞ performances of the closed-loop system are under control. In contrast to most of the current sliding surface design schemes, in this new framework, the level of control effort required to maintain sliding is penalized. The proposed method for the design ...

The impact of financial challenges on the profit of a supply chain, have caused the researcher to model the supply chain network by considering the operational and financial dimensions. Also, the establishment of a closed loop supply chain (CLSC) network has a high effect on economic profit. So, the purpose of this study is to design a stochastic closed loop supply chain network by considering ...

In this study, we introduce the topic for exponential stability criterion of delayed linear system via intermittent feedback control. Utilizing concept fundamental control is designed as continuous-time controller to generate open-loop predictions states, foreseeing behavior in future over time-varying delay defined (2.2). The open loop trajectory would declare set I(t) into a closed-loop For n...

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 ...

The paper deals with the problem of sampled-data polynomial modal control for a linear continuous-time periodic plant with delays at the input and the output of the sampled controller. It is assumed that the plant and the digital controller have the same period. The characteristic matrix of the closed-loop system is constructed. An algorithm is given for constructing the set of causal discrete-...
