This paper presents a novel scheme for the direct estimation of a PID controller parameters(Kp, TI, Td).The proposal discussed here is only applicable to first and second order stable systems. The formulation begins with system parameter identification (Transfer function of the process), which was calculated by applying weighted-recursive least square method. The pole zero cancellation technique was applied to estimate PID controller parameters ;which in-turn results into the matched coefficients of the system parameters to the Controller parameters. An additional tuning parameters 'α' is proposed in our method, which provides an additional flexibility of tuning the response time of the controller without disturbing the controller parameters. The proposed scheme was bench marked using real time cases of DC Motor speed control and Cruise Control. The effectiveness and robustness of the proposed auto tuning algorithm is verified by the simulation results.
