PID controllers provide satisfactory performance and widely used in many of control processes due to their simplicity. An appropriate controller tuning provide a good performance of the controller to perform well. Some processes are difficult to control especially processes with difficult dynamic. In this report, the author will discuss mostly on two types of dynamic processes which are time delay process and inverse response process. A model of each dynamic process is obtained to studies their behaviour using various type of tuning method such as internal model control (IMC), SIMC, Ziegler-Nichols (Z-N) and Tyreus-Luyben (T-L). Matlab Simulink is used to observe their behaviour and simulation result on each process. This is because difference tuning methods perform difference controller response. The project is successfully done and achieved the objectives.
