In this paper, a model-free PID controller design method has been proposed using simple closed loop set-point experiments. The unit step closed loop test is performed in a classical unity feedback configuration with the proportional control gain Kc0 only. For most of the processes Kc0 is chosen such that overshoot may be in between 10% to 50% of steady state value. From the closed loop set-point test (CLSP), the amplitude of the first peak and the second peak (Cp1 and Cp2), their corresponding time (tp1 and tp2) along with the steady-state value, Css are obtained. The response data is generated by applying set point change and using Gc1 (s) with proportional gain Kco only. By using the resulting set-point response data, an approximate second order plus dead time (SOPDT) transfer function Gp (s) is obtained. Once Gp (s) is obtained, then the PID parameter are obtained using direct synthesis (DS) method to achieve the enhance disturbance rejection. Simulation studies shows the supremacy of the proposed scheme over recently reported method from the literature.
