Abstract
Sliding mode control methodology (SMC) is considered as an efficient technique in several aspects for control systems. Nevertheless, applying first-order sliding mode control method in real-life has what so-called chattering phenomenon. Chattering is a high frequency movement that makes the state trajectories quickly oscillating around the sliding surface. This phenomenon may lead to degrade the system effectiveness, or even worst it may lead to fast damage of mechanical parts of the system. Presently, the major solutions to this drawback are asymptotic observers and high-order sliding mode control. The higher order sliding mode control is an expansion of the conventional sliding mode, and it can cancel the imperfection of the conventional sliding mode methodology and sustain its advantages. Since the second-order sliding mode controller, for example, super twisting algorithm, has unsophisticated construction and requires a lesser amount of acquaintance, it is the most extensively technique that used in the higher order sliding mode methodology. However, in several cases, the chattering amplitude result from conventional method is less than the one result from super twisting algorithm. In this thesis, the describing function method, most suitable technique to analyze nonlinear systems, is used to make comparison between the two methods, the conventional and the super twisting sliding mode control. A simulation is performed to confirm the results that describing function method shows. Several situations illustrate the efficiency of first order sliding mode control over the higher order sliding mode control are represented.
