Computer aided frequency domaın analysis of control systems

IV SUMMARY M.S. Thesis COMPUTER AIDED FREQUENCV DOMAIN ANALYSIS OF CONTROL SYSTEMS Hanifi 6ÜLDEMİR University of Fırat Graduate School of Natural and Applied Sciences Department of Electrical and Electronics Engineering 1991, Page: 70 In this study, Root locus methods and Bode diagrams which play an important role in designing automatic control systems were considered and computer programs that perform these two topic were developed. After brief description of Root locus and Bode diagrams a computer program was developed for Root Locus as K varies in the range between -» and +.. On the other hand Bode diagram was obtained for a constant value of K by another computer program. For both computer programs, the transfer function polinomial whose degree £ 10 may be supplied by either in factors or coefficients. The program gives the necessary values of phase and gain margin and information about the stability of the system for the designing of controllers.
