The paper presents the tuning method for the PID (Proportional Integral Derivative) of special processes consisting of self-balance with overshoot and self-imbalance with inverse response. It is a continued study of process identification by numerical method and PID controller design based on robust viewpoint. The self-balance process with overshoot is identified by the second order plus dead time with a negative zero (SOPDTZ), while the self-imbalance process with inverse response is modeled by integrating plus first order plus dead time (IFOPDT). To gain robust PID for processes, it requires typical designs. While the SOPDTZ needs a filter of first order lag, the IFOPDT requires to supplement integrating element for controller. For illustration, the detail identification and tuning procedures are presented via an example for each of the processes.
