要約(日本語): PID control schemes have been widely used in most process control systems for a long time. However, it is a very important problem how to choose PID parameters. Because these parameters give a great influence on the control performance. Especially, it is difficult to tune these parameters for time-varying systems. In this paper, a new self-tuning PID control scheme is proposed for such systems, which is based on the discrete-time IMC tuning method. Then, the user-specified parameters included in the newly proposed scheme can be adjusted by using a real-coded genetic algorithm in an on-line manner.
