Analysis and Simulation of Two-Step Phase Plane Division Control

Firstly,after a theoretical analysis of the phase plane divisional control,for extending the application area and easily tuning the parameters,an improved controller was presented.Secondly,after the stability analysis of the high-order system,both the method of confirming K'o and the parameters adjusting principle of this controller were introduced.Finally,with several high-order simulation examples,the influences of the first controller,the second controller and the acting time in this system on the system...
