The purpose of this thesis is to find suitable ways to design feedback compensators for high order systems by using Root-Locus methods. As a starting point we will examine a motor amplidyne system and a position control system that were previously designed using Bode methods. Then we generalize the method and extend it to other systems. The final subject of this thesis is to design feedback compensators as filters by using state feedback coefficients to define zeros of the filter, then we...

Root locus techniques are used infrequently in the design of tachometer and acceleration feedback compensation, for feedback control systems. A root locus stability criterion is discussed, which has the capability of handling more than one variable coefficient in the characteristic equation. This stability criterion is applied to the analysis and design of tachometer and acceleration feedback compensation. The design of cascase compensation is attempted, and the difficulties of designing this...

A design technique for root placement with full state feedback using transfer functions for all-pole plant is presented in this thesis. A number of examples are presented to demonstrate the procedure with this design technique when all the system states are available to be measured and fedback. The design procedure presented is applicable for linear, time invariant (LTI) systems in the s-domain for continuous time. In order to get the roots at desired locations by transfer function methods very...

Lag-lead compensators are well known in automatic control engineering. They have 4 parameters to be adjusted (tuned) for proper operation. The frequency response of the control system or the root locus plot are traditionally used to tune the compensator in a lengthy procedure. A first order with an integrator process in a unity feedback loop of 67.3 % maximum overshoot and 12 seconds settling time is controlled using a lag-lead compensator (through simulation). The lag-lead compensator is...

— The present paper is focused on linear quadratic regulator (LQR) synthesis. It is evident that the solution of the problem leads to finding a solution of symmetric root locus (SRL) problem. It is proven and analytical evidences is also presented that by using SRL synthesis method and further application of LQR method guarantees stability, minimum phase and gain margins of the closed loop system. The presented mathematical relationships are further proven with experimental investigation in...

This thesis discusses the modification of and additions to an existing Optimal Systems Control FORTRAN Program (OPTSYS) originally obtained from Professor Arthur E. Bryson of Stanford University. This program has been subsequently redesigned to run interactively on the IBM 3033 VM/CMS by lieutenant Commander John G. Hoden, and additions by Commander Harry A. Diel provide the user with a highly accurate graphic time response to a system designed using the OPTSYSX program. The addition of the...

This thesis takes five FORTRAN IV programs from \"Computer Programs for Computational Assistance in the Study of Linear Control Theory\" by Melsa and Jones and translates them into a microcomputer BASIC language to run on an inexpensive microcomputer system. Three of the five programs are state variable programs. They are BASMAT for basic matrix manipulation, RTRESP for rational time response, and GTRESP for graphical time response. Two are transfer function programs, FRESP for...

In this thesis the development of the Digital and Analog Control System Analysis Program (DACSAP) is discussed. DACSAP is an interactive computer aid for the design and analysis of linear, single input/output feedback control systems. DACSAP is user friendly; it uses menus for option selection and prompted data entry. The program will analyze systems which are described by transfer functions written in the s, z, w, or w' domains. The program will manipulate the transfer functions of multi-loop...
