A SIMPLE ROBUST PID CONTROLLER DESIGN METHOD BASED ON SINE WAVE IDENTIFICATION OF THE UNCERTAIN PLANT

Štefan Bucz – Ladislav Marič – Ladislav Harsányi – Vojtech Veselý

   The paper deals with the development and application of a new simple empirical approach to the design of robust PID controllers for technological processes in industrial practice. The main advantage of the proposed approach is the possibility to specify the required performance before the design algorithm implementation. Identification of characteristic data of the black-box type plant with varying parameters is carried out using the sine wave excitation signal, thus allowing to design the controller without necessarily knowing the mathematical model of the plant. The proposed approach has been verified on a real-world physical process.

Keywords: empirical methods, characteristic data of the plant, excitation signal, robust stability, robust performance
