چکیده
In this paper, the sixteen plants theory (SPT) is applied to a hydrogenerator system model, which incorporates parametric uncertainty, in order to design a robustly stabilizing PI controller, which enhances the stability characteristics of the plant over a variety of ope-rating points. Key-Words: Power systems, parametric uncertainty, robust stabilization, Kharitonov theorem.

Optimal Output – Feedback a Multirate Stabilization Techniques Applied to the Design of Excitation Controllers of a three Phas
In this paper an optimal control strategy, is used to design a desirable excitation controller of a hydrogenerator system, in order to enhance its dynamic stability characteristics. The proposed control strategy based on Two-Point-Multirate Controllers (TPMRCs) is readily applicable in cases where the state variables of the controlled plant are not available for feedback, since TPMRCs provide t...
متن کاملLoad-Frequency Control in a Deregulated Environment Based on Bisection Search
Recently several robust control designs have been proposed to the load-frequency control (LFC) problem. However, the importance and difficulties in the selection of weighting functions of these approaches and the pole-zero cancellation phenomenon associated with it produces closed loop poles. Also the order of robust controllers is as high as the plant. This gives rise to complex structure of s...
متن کاملDesign of Nonlinear Robust Controller and Observer for Control of a Flexible Spacecraft
Two robust nonlinear controllers along with a nonlinear observer have been developed in this study to control a 1D nonlinear flexible spacecraft. The first controller is based on dynamic inversion, while the second one is composed of dynamic inversion and µ-synthesis controllers. The extension of dynamic inversion approach to flexible spacecraft is impeded by the non-minimum phase characteristi...

An optimal control strategy based on Two-Point-Multirate Controllers (TPMRCs), is used to design a desirable excitation controller of a hydrogenerator system, in order to enhance its dynamic stability characteristics. In the TPMRCs based scheme, the control is constrained to a certain piecewise constant signal, while each of the controlled plant outputs is detected many times over a fundamental...
متن کاملA Thorough Comparative Analysis of PI and Sliding Mode Controllers in Permanent Magnet Synchronous Motor Drive Based on Optimization Algorithms
In this paper, the speed tracking for permanent magnet synchronous motor (PMSM) in field oriented control (FOC) method is investigated using linear proportional-integral (PI) controller, sliding mode controller (SMC) and its advanced counterparts. The advanced SMCs considered in this paper are fuzzy SMC (FSMC) and sliding mode controller with time-varying switching gain (SMC+TG) which can effec...
