Wherein
Derivation of the formula (4) to obtain
The formula (5) is subjected to Fourier change from time domain to frequency domain to obtain a transfer function
It can be seen from the formula (4) that the frequency ω of the pulse of the stepping motor is increased exponentially along with the time t, at this time, the frequency ω can be greatly increased within a relatively short time t, the rotating speed of the stepping motor can also reach the required rotating speed within a relatively short time, and the stepping motor can realize no step-out and rapid start-stop. When the stepping motor starts with a load, because the static inertia of the motor is large during starting, the stepping motor is accelerated and decelerated with small acceleration, after the rotating speed of the stepping motor is slowly increased, the rotational inertia of the motor is simultaneously reduced, and the stepping motor can be accelerated and decelerated with large acceleration. Similarly, when the stepping motor is about to stop running, the rotating speed of the stepping motor is slowly reduced, and the rotational inertia of the motor is gradually increased, so that the acceleration of the stepping motor should be accelerated and decelerated firstly and then decelerated secondly, the process can prevent the overshoot and the step loss generated by the motor, and the acceleration and deceleration curve of the stepping motor is an S-shaped acceleration and deceleration curve, and the S-shaped acceleration and deceleration curve can not only prevent the step loss and the overshoot of the stepping motor, but also has reasonable acceleration and deceleration distribution and can avoid the flexible impact of the motor.
