Abstract:

The system for stabilizing platform of a ship carried antenna a nd its core component are discussed in this study. Relevant mathematics model of these components are established. Thus, the dynamic model of the system is deduced including the effects of friction, inertia and torque motors. Using Solid Works, we built the mechanical structure, including the servo machine of each part of the system. The system under consideration is a system with strong interactions between three channels. By using the concept of decentralized control, a control structure is developed that is composed of three control loops, each of which is associated with a single-variable controller. First, PID controller was applied; then, Takagi-Sugeno (TS) fuzzy controller was used for controlling the platform. Simulation tests were established using Simulink of Matlab. The obtained results have demonstrated the feasibility and effectiveness of the proposed fuzzy approach comparing to the PID controller. Simulation results are represented in this study.
