Analysis Of Nine-Controller Control Force And The Tackle Of Non-linear System

Nine-Point Controller is a new type of intelligence controller. Based on the conditions of system course, it takes apart phase plant into nine zones. These zones are called work condition, with every work condition according to various control strategies given by K_i.Nine-Point Control System is the system control by Nine-Point Controller. In order to make Nine-Point Controller applicable to on-spot control, (lie prime task is to analyze each control force. The paper illustrates the influence of control force on the response of second order surging system. From this paper's analyzing, the partition of phase plane is sound.The control of Nine-Point Controller is a special structure, with the error signals not entering into the control passageway. The function of feedback passageway is to decide current condition and give corresponding control force. Under one-work conditions, the control force is invariable. Here the system is similar to open-loop control system.The second-order system is universal in control field. So the analyzing of it is representative. The paper explains the control force with the center of performance index.The static error is an important index of the control system. In Nine-Points Controller control system, it utilizes K₀ control force achieving the static error requirement. The condition of Ko=0 could Fit the second order in most control environments.To some dynamic index, for example ascending time or pulse, corresponding control force could control it. By these methods, the system could meet the demanding of the results.The nonlinear system exists in the control fields universally. The research of these systems is very important in on-spot control. Due to the special control structure of Nine-Point Controller, the adjustment of control method is easier than customary control system. The static characteristic of control force takes the key-role in the nonlinear system's control.
