A Novel Low Complexity Fast Response Time Fuzzy PID Controller for Antenna Adjusting Using Two Direct Current Motors

Objectives: A novel PID Controller (PIDC) for the purpose of adjusting an antenna in 360 degrees range by direct current (DC) motors using Fuzzy method is designed and simulated. Methods: For this, first, an accurate model for DC motor in simulations is developed- that can be replaced by any other dynamic, for e.g., a high power low speed motor, however, the response in this case will be different. The controller mentioned uses the Mamdani type in two working modes with 3 and 4 inputs setting the full control of two independent DC Motors (DCMs). Findings: Clearly, the modes with 3 and 4 inputs occupy 27 and 81 commands respectively to have smooth overshoot and under shoot responses. Some of the parameters are acquired experimentally that can be modified for various applications, although these values are also remarked for the possible re-simulation by the readers. Application: However the PIDCs have many applications in industry, the main application of our PIDC is intended for radar systems where the antenna needs to quickly rotate in order to accurately receive the reflections from certain paths.
