Patent ID: 11880128

Abstract:
A non-sensor type closed-loop stabilization control algorithm comprises the following steps: 1, reading all voltages Vk−1 and currents Ik−1 for driving a multi-axis stabilization motor; 2, calculating and outputting all coil resistances Rk−1 in the multi-axis stabilization motor; 3, reading all the coil resistances, voltages and currents in the steps 1 and 2, and calculating and outputting counter electromotive force Ek−1 of all the coils in the multi-axis stabilization motor; 4, reading an stabilization compensation angle θk, each coil resistance and the counter electromotive force, and calculating and outputting a closed-loop stabilization control Fk; and 5, then waiting for a time step k=k+1, and repeating the steps in the steps 1 to 4. It aims to add a closed-loop control element to a motor without a sensor to achieve an excellent stabilization effect and to reduce the risk of image blurring caused by resonance.
