“…where L s the self-induction, the first item of ( 6) is resistance voltage drop, the second item is the potential induced by the change of flux linkage in phase winding caused by the change of rotor position, the third item is the back EMF, e(θ) which was caused by the change of current. The motor working in single channel mode can be regarded as a conventional HSM; in the case of two stator phases, the back EMF can be approximated by a sinusoidal function [28] as shown in e a (θ) = −pψ m sin(pθ) dθ dt e b (θ) = pψ m cos(pθ) dθ dt (7) where ψ m is the maximum magnetic flux, p is the number of pole pairs.…”

Stepping motors are highly preferred in spacecraft applications because of their simple structure, convenient control and lack of accumulated error. In satellite antenna drive systems, reliability and fault tolerance have been paid more and more attention. Accordingly, to enhance the reliability of the electrical system in the field of aerospace, the redundancy technology, which can effectively improve the system reliability while reducing the requirements of components, was applied in the design of hybrid stepping motors (HSM), a dual-redundancy two-phase HSM which has two sets of stator windings was designed in this paper. The mathematical model of stepping motor and the specific structure parameters of the motor are given. The torque-frequency characteristic was regarded as the key to measure the performance of the motor proposed in this paper. The results of 3-D finite element modeling are presented. The corresponding performance experiment on the designed motor was carried out and both the simulation results and the experimental results verified the validity and superiority of the dual redundancy HSM.

This paper proposes a Barnacles mating optimizer‐based multi‐resolution proportional‐integral derivative (MRPID) controller for precise speed control of the hybrid stepper motor (HSM). The proposed approach is a barnacle mating optimizer (BMO) control scheme. The main objective of this approach is to use the MRPID controller to improve speed control in particular and uncertain conditions. The BMO is utilized to create the proposed MRPID controller. The proposed converter has a low switching voltage and uses a low input current. The proposed converter supplies a large amount of power to the voltage source inverter (VSI), which converts DC to AC and then supplies it to the HSM. The HSM can be utilized in various settings, including robots and factory applications. Then, the performance of the proposed system has been evaluated in the MATLAB platform and compared with various existing systems. The existing adaptive neuro‐fuzzy inference system (ANFIS) and the moth flame optimization algorithm (MFO) methods are used to validate the efficiency of the proposed controller. The proposed system rise time is 0.0007, the settling time is 0.1, the recovery time is 0.221, the AMU is 1.205, the IAE is 0.1034, and the SSE is 0.234. According to the simulation findings, the suggested system is statistically significant.
