Analytical Solutions for Lag/Lead and General Second Order Compensator Design Problems
نویسنده
چکیده
This paper presents a simple method for determining analytical solutions to lag/lead cascade and general second order compensator design problems in the frequency domain. Only linear and quadratic equations are used in the proposed approach. Results obtained here can be used to eliminate conventional graphic-based trial-and-error method used in past and contemporary control textbooks, which are tedious and time-consuming, and rewrite them into simple and analytical non-trial-and-error steps.

The Analytical Solution of the Lag-Lead Compensator
In this paper, we first give the analytical solution of the general laglead compensator design problem. Then, we show why a series of more than 5 phase-lead/phase-lag compensator cannot be solved analytically using the Galois Theory.

متن کاملPhase Lag and Lead Weighting in Linear-quadratic Control
The use of frequency-weighted performance indices in linear quadratic (LQ) optimal control has been the subject of recent r e ~ e a c h ' ~ . The primary motivation for frequency-weighting is the possibility of enhancing the robustness of LQ designs in critical frequency bands. A preliminary study3 of the case where high frequencies in the control are weighted more heavily has shown that the op...
متن کاملRestoring Motor Functions in Paralyzed Limbs through Intraspinal Multielectrode Microstimulation Using Fuzzy Logic Control and Lag Compensator
In this paper, a control strategy is proposed for control of ankle movement on animals using intraspinal microstimulation (ISMS). The proposed method is based on fuzzy logic control. Fuzzy logic control is a methodology of intelligent control that mimics human decision-making process. This type of control method can be very useful for the complex uncertain systems that their mathematical model ...
متن کاملDesign of Grid connected Photovoltaic Inverter with Resonant Harmonic Compensator
The reduction of high harmonic content in the grid side current is achieved by different harmonic compensating techniques. In order to accomplish it, selective harmonic compensation is carried out in grid-connected photovoltaic inverters by means of resonant harmonic compensators. The harmonic compensator shown in this paper is lead lag compensator. This paper shows a systematic design procedur...
