Abstract:
T This paper presents the design of an adaptive terminal sliding mode controller based on type 1 and type 2 fuzzy sets for the active gravity compensation system. This system is designed to simulate the microgravity conditions in terrestrial environments and plays an important role in testing the performance of spacecraft before launch. The dynamic equations of the active gravity compensation system of the suspension are modeled using Lagrangian approach. The design of the proposed controller aims to improve the stability and accuracy of the system in the presence of disturbances and uncertainties. In this context, the use of type 1 and 2 fuzzy logic has increased the flexibility of the controller in dealing with uncertainties and allowed the reduction of chattering and faster convergence to the desired conditions. The results of numerical simulation in the MATLAB environment have shown that this controller was able to reduce the output errors of the system with high accuracy and provide desirable performance in tracking reference sections.
