Design of Sliding Mode Controller With Proportional Integral Sliding Surface for Robust Regulation and Tracking of Process Control Systems

Abstract: This paper deals with the design of sliding mode controller (SMC) with proportional plus integral sliding surface for regulation and tracking of uncertain process control systems. However, design method requires linear state model of the system. Tuning parameter of SMC has been determined using linear quadratic regulator (LQR) approach. This results in optimum sliding surface for selected performance index. Matched uncertainty is considered to obtain the stability condition in terms of its upper bound. A conve… Show more

“…It can be observed from Table III that the newly obtained PI controller based on weighted geometric center method outperforms the auto-tuned PI controller in terms of maximum overshoot, rise time, settling time and lesser controller efforts. Example: 4 Liquid level system Consider the transfer function of liquid level system given by eq.25 [13] The PI controller parameters computed by using Eq.22 and Eq.23 are obtained as K p = 0.005443 and K i = 0.00108. The output response and control signal shown in Fig.19.…”

“…Sự ổn định của SMC có thể được đảm bảo bằng cách tạo ra các điều kiện ổn định. Ngoài ra, hiệu quả động học mong muốn có thể đạt được bằng cách lựa chọn và thiết kế mặt trượt thích hợp [1]. Tuy nhiên, đối với biên độ của luật điều khiển trượt nếu không được lựa chọn phù hợp sẽ gây ra hiện tượng chattering [1], [7], [8].…”

“…The SMC strategies based on different forms of PID sliding surface have been widely used in many practical systems. In [25]- [28], SMC strategies based on the PID sliding surface were developed to the process control systems, robotic manipulators, quadcopter and semi-active vehicle suspension, respectively. For 300 years, Fractional-order theory has been studied by scholars as pure mathematics theory.…”
