PID controller is the most common used feedback controller. Many process control problems can be solved by ocnventional PID controllers. The main reason that PID controllers are so widely used is its simple structure which have been proved to be very robust with regard to many comonly met process control problems (disturbances, nonlinearities, etc.). There are many methods of tuning PID controllers and they are mostly reliying on the knowledge and skill of the controll engeneers. Most common methods used in PID tuning are Ziegler-Nichols method [1], Cohen-Coon method [2], tuning rules based on minimisation of different error criteria [3], neural networks based methodologies [4], fuzyy logic [5], and etc. In this paper, a set of tuning corellations is obtained for three different process dynamics systems which can be described as first order proces plus time delay (FOPTD), second order process plus time delay (SOPTD) and secont order process plus time delay with lead (SOPTDLD). Tunning parameters are derived so they minimize integral absolute error and the solutions are given as a set of mathematical exspressions that can be conventionally used in practice.
