We generalize the IMC approach for cascade control systems with a generalcascade control structure and show how to obtain PID tuning parameter values forgeneral process models. General processes are divided into two parts. One includesintegrating, unstable processes and stable processes with poles near zero. The otherincludes normal stable processes. For these processes, IMC controllers to give desiredclosed loop responses are obtained and converted to PID controllers. The PID controllerstuned by the proposed method give superior performances to the performances of thePID controllers tuned by other design methods.
