Abstract:

A kind of mechatronics electrical actuator control system used by unmanned aerial vehicle (UAV) was introduced. The layout of actuator adopted with brushless DC motor, harmonic reducer, shaft coupling, rotary transformer and servo arm in tandem to make the structure compact and small. The controller was based on DSP+CPLD, PI control algorithm, position protection and current protection logic were used to enhance the reliability of the system. The driver based on the intelligent power module simplified the circuit design. The experimental results show that the system meets the requirements of control performance and has the characteristics of high power density.

Key words: electric actuator, brushless DC motor, DSP+CPLD, control circuit
