Design of a High-Speed Rapier Loom Control System Based on a Mixed Current Attenuation Algorithm

“…In this paper, the closed-loop control of the current is realized by software. For current closed-loop control, PID adjustment is the most mature and widely used control method [27][28][29]. Since the stator current of the stepper motor cannot follow the rapid change of the given reference value, adding the derivative term will cause the controller output to change excessively and will reduce the control effect of the motor, so only PI adjustment is adopted.…”

The Subdivided Driving System Used in Stepping Motor

“…Then, these pulse sequences with equal frequency and unequal width are PWM waveforms [14]. According to the principle of area equivalence, PWM waveform and sine half wave are equivalent.…”

“…The comprehensive performance of the stepping motor, the structure of the stepping motor itself, and its driving technology. The closed step motor is also called pulse motor [1].…”

Self-learning current optimizing control for conventional stepping motor drive technique based on step pulses

“…As an outcome, both K p and T i depend on the mechanical damping and inertia and the torque constant. In De Viaene et al (2018b), the latter problem is tackled by defining a sensing procedure to determine the settings of an adaptive proportional-integral (PI)-controller with the settling time of the current reduction as design constraint. In addition, the optimal load angle highly depends on the operating point of the stepping motor (De Viaene et al, 2019).…”

“…Unfortunately, the assessment of these parameters are difficult as their values vary with the motor operating conditions (Bertoldi and Atanasiu, 2009). In practice, the estimator and control techniques in De Viaene et al (2018a), Derammelaere et al (2017), De Viaene et al (2018b), and De Viaene et al (2019) are not directly implementable. Therefore, in this paper, it is preferred to shift the focus from the load angle to the cos ( ϕ ) .…”
