Piezoelectric ceramics are widely used in precision measurement and precision positioning, but its nonlinear characteristics seriously affected its application. Thus, firstly input voltage and output displacement data of piezoelectric ceramics are collected by the experiment, the nonlinear characteristics of piezoelectric ceramics is analyzed. Then a piezoelectric ceramic linear model is established using recursive least squares algorithm based on input and output signal. The identification results show that the algorithm is effective. Finally PID controller is designed and the controller has better control effect.

Conventional Methods

Sequential auto-tuning based model identification is a closed loop approach, which has an extensive benefit compared to conventional methods because of user defined manipulated gain to the process within the verge of instability. Model parameters estimation of multi input multi output process is challenging because of existence of multivariable interaction among the variables. In this paper ideal relay is used as a sequential basis for binary distillation column in real time. Obtaining sustained oscillations in conventional methods is based on trial and error, benefit of relay is that oscillations can be generated as scaling of user defined gains. Predictive PI control algorithm is implemented. Results depicts the efficiency of methodology and importance of anti-reset term in the algorithm.
