Design and Verification of Motor Direct-driven Actuator for FES
A motor direct-driven actuator was designed to enhance the performance of fast earth switch(FES).This motor direct-driven actuator includes mechanical drive
main circuit of motor
and digital signal processor(DSP)for control with peripheral circuits.And the main circuit section of motor includes a rectifier circuit
a capacitor discharge circuit
and an inverter circuit.The DSP uses the TMS320F28335 from Texas Instruments
and its peripheral circuit includes an IGBT power driver board
a current acquisition circuit
and a speed/position acquisition circuit.The control algorithm of whole system was simulated in MATLAB/Simulink
and the results indicate that the motor direct-driven actuator can meet the requirements for FES closing operation.In addition
characteristic test of an FES equipped with the motor direct-driven operating mechanism showed that its closing speed meets the requirements of parameters
