Patent ID: 10707794

Abstract:
A multicopter includes a body, propellers, each of which is rotated by a motor to generate lift for the body, a main controller configured to supply a speed instruction signal to the motor, a supply circuit configured to supply a torque current signal and a field current signal obtained from the motor, and a motor drive control device. The motor drive control device includes a control signal generation circuit configured to generate a torque current instruction signal and a field current instruction signal in response to the speed instruction signal, a vector control circuit configured to receive the torque current signal, the field current signal, the torque current instruction signal and the field current instruction signal, and output control signals so that the torque current signal and the field current signal from the motor coincide with the torque current instruction signal and the field current instruction signal, respectively, and a motor driver circuit configured to accept the control signals from the vector control circuit to control the motor.
