Claim 0:
1. An application circuit using a non-sensor type closed-loop stabilization control algorithm, the application circuit comprising a controller, a driving circuit, an induced circuit and a multi-axis stabilization motor, wherein,
the driving circuit outputs an stabilization control instruction according to the non-sensor type closed-loop stabilization control algorithm to drive the multi-axis stabilization motor:
the induced circuit detects all voltages and currents output to for driving the multi-axis stabilization motor by the driving circuit, and outputs all the voltages and currents to the controller, wherein
the controller executes the non-sensor type closed- loop stabilization control algorithm to:
step 1, read all the voltages Vk−1 and currents Ik−1 through a resistance calculation module;
step 2, calculate and output all coil resistances Rk-1 of all coils in the multi-axis stabilization motor based on the voltages and currents;
step 3, read all the coil resistances, voltages and currents by a counter electromotive force calculation module, wherein the counter electromotive force calculation module calculates and outputs counter electromotive force Ek−1 of all the coils in the multi-axis stabilization motor based on the coil resistances, voltages and currents;
step 4, read a stabilization compensation angle θk, all the coil resistances and the counter electromotive force through a closed-loop stabilization control module, wherein the closed-loop stabilization control module calculates and outputs a closed-loop stabilization control Fk based on the stabilization compensation angle, all the coil resistances and the counter electromotive force; and
step 5, wait for a time step k=k+1, and repeating the steps in the steps 1 to 4, wherein k is an integer.
