Title: Adaptive control system
Inventor: ITO MASAMITSU
IPC: G05B13/00
Filed: 1986-01-29
Abstract: PURPOSE:To attain the optimum process control at all times regardless of the change of process characteristics by estimating the change of the process characteristics only when needed and performing usually the optimization of the control parameter. CONSTITUTION:An optimum control parameter arithmetic part 3 calculates an optimum parameter based on the identification data collected by a data collecting part 2. A bidirectional adaptive control learning part 4 chooses the adaptive exponent of an object process based on said optimum parameter. This adaptive exponent is fixed and the process characteristics are estimated. Based on the result of this estimation, the optimum control value is obtained and stored in a pair with said adaptive exponent. These operations are repeated to obtain a parameter gathering against the entire operation of a process. Thus an approximation curve is obtained for the stored data. These processes to collect data and obtain the approximation curve are carried out only when needed. While a PID control output arithmetic part 1 obtains the optimum parameter from an obtained adaptation curve and performs the control arithmetic operation by means of said optimum parameter.
