The study of an electromechanical actuator with a resolver as the position sensor
Space electromechanical actuator uses a permanent magnet synchronous motor as the servo component, which features in small dimension, high accuracy and reliability. At the same time the position signal of the electromechanical actuator is significant for the system performance. Resolver is widely used due to its high temperature tolerance, humidity resistance, impact resistance, anti-jamming and other advantages. In this paper, the position sensor of the electromechanical actuator servo system uses a resolver as the rotor position sensor, designes the resolver signal processing circuit that can get absolute position signal directly, and translate it into digital corresponding quantity. Decoder chip and controller chip can be linked through the data bus, I/O port and SPI port in order to interface with the digital signal processor (TMS32F2808) chip which can receive and process the signals of the rotor position. With the space vector control strategies of Permanent magnet synchronous motor, better performance has been achieved. Experiments show that the design is compact, high reliability, high precision and has achieved satisfactory results.
