Abstract: | A nonlinear model of an electromechanical actuator (EMA) system for aerofin control is presented. The EMA is realized with a permanent magnet brush DC motor controlled by a constant current driver. In this paper we introduced a simulation model that includes nonlinearities of the motor driver. A PID position controller was designed using the simulation model, although it was impossible to develop a linear model. The simulation results have been of the great importance for understanding the system behavior and successful control system implementation. The proposed control system has experimentally been validated on a test bench. The EMA-AFC test bench is designed to provide real operating conditions. The text was submitted by the authors in English. |
