This paper presents a discrete sliding mode controller for higher order systems without using model order reduction techniques for single input single output systems. The proposed controller is designed with discrete form of PID as a sliding surface. To find the PID sliding surface controller tuning parameters, the traditional method of PID design or pole placement method can be used. The designed controller has flexibility in terms of range of the parameters to decide the stability and robustness of the closed loop performance and existence in terms of Lyapunov function and/or stability. Generally it is difficult to design proper controller due to inaccurate identified model of system or its parameters and external unmesaurable disturbance. The proposed controller has a simple and flexible structure having a set of tuning equations as a function of the desired performance of the systems. The discrete form of sliding surface and system states provide highly useful information to control necessary parameters of the interest for many higher or lower order systems. The systems available in real time or plant model identified by different method in the context of design of the controllers results in higher order; therefore it is necessary to direct the automation applications of systems towards higher order systems. In this paper, the examples are simulated using Mathwork’s MATLAB to show and compare results proposed law with prevalent available controllers. |
