| Abstract: | In this paper, the computing method and formulas of departure angle of root loci for the closed loop control system with multiple poles are advanced and the computer program for seeking root loci is compiled using the Newton-Raphson iterative method which is put forward. Using this computer program the place of root loci on the complex plane and gains of all point in root-loci are obtained and the complete rout locus curve is drawn. |
