Abstract: A new algorithm of characteristic model of human simulated intelligent control(HSIC) is provided on the basis of phase plane e-è analysis.This controller divides the system dynamic process into some running modes and constructs relationships between the basic performance of the system response and the dynamic process divisions indirectly.The control structure is of open-closed-loop,that is to say,a closed-loop control system in which the opened-loop is magistral,and it has a simple control mode.At the same time,this paper combines fuzzy logic control with HSIC,and presents a new intelligent controller,i.e.fuzzy HSIC.Its domain of inputs and output linguistic variables has direct relations with the phase plane divisions of the new characteristic model algorithm of HSIC,and the control rule table is determined directly by the logical control rules of the new algorithm.The simulations show that it is convenient for the improved HSIC algrithm to construct the fuzzy controller and it has better performance in robustness and anti-disturbance.
