Most of the chemical processes can be controlled with proportional-integral controllers. For this reason, it is crucial to determine the optimum control parameters of proportional integral controllers. In this thesis, it is aimed to obtain the correlations which relate the optimum proportional integral controller parameters to process parameters for different types of process models.With this study, servo and regulatory control correlations for proportional integral controllers are obtained and presented in several tables for the process model types of first order plus time delay (FOPTD) and second order plus time delay (SOPTD) for the objective of minimizing each performance criteria value (integral of absolute value of the error (IAE), integral of the time-weighted absolute value of the error (ITAE), integral of the squared value of the error (ISE) and integral of the time - weighted squared value of the error (ITSE)), separately.
