“…The characteristics of electromagnetic torque components are one of the key points to study the torque output stability of UHSPMSM. The UHSPMSM is a complex coupling system [19][20][21][22]. Its torque output stability is closely related to electromagnetic parameters, mechanical parameters, and electronic control parameters.…”

The ultra-high-speed electric air compressor (UHSEAC) is affected by the electromagnetic torque components of the ultra-high-speed permanent magnet synchronous motor (UHSPMSM) during wide-range speed regulation, resulting in intense speed fluctuation. Electromagnetic torque components are generated by the effects of permanent magnet field harmonics, stator slotting, and current harmonics. It is very important to conduct simulation comparisons and theoretical descriptions of different sources of pulsation factors. In this paper, firstly, the electromagnetic torque model of UHSPMSM with a rated speed of 80,000 rpm is constructed and verified by an experimental bench. Secondly, the electromagnetic torque components of UHSPMSM are extracted on the basis of the electromagnetic torque model. Finally, the electromagnetic torque components’ characteristic law is investigated under different ultra-high-speed operating conditions. The results show that under ultra-high-speed operation, the frequency and amplitude of electromagnetic torque components become larger with increasing speed. And the amplitude of electromagnetic torque components becomes larger with increasing torque. This paper constructs the observation object of the high-frequency state observer and does the preliminaries for the design of the UHSEAC controller.

“…More further, regarding the delayed processing, the authors (Keighobadi, Pahnehkolaei, et al, 2022a) introduce a fractional-order delay compensation system to handle the input delay. In Hua et al, 2022, the authors solve the input delay of a coupling PMSM by constructing LKFs, and the method can solve larger time delays compared to the result (Keighobadi, Pahnehkolaei, et al, 2022a). However, they ignore the effect of time delays, which may lead to poor performance and system instability (Lu et al, 2019).…”

This paper presents a neural adaptive finite-time dynamic surface control for the permanent magnet synchronous motor system with time delays and asymmetric time-varying output constraint. The core challenge is how to address the time delays and asymmetric output constraint when designing a finite-time control scheme. Given this, a proper Lyapunov–Krasovskii functional is introduced to address time delays, and a nonlinear transformation function is considered to convert the output-constrained problem into an unconstrained one. Then, a neural adaptive finite-time dynamic surface control approach is devised in the finite-time backstepping framework, which applies neural networks to estimate the unknown nonlinear functions and introduces first-order filters to solve the “explosion of complexity” problems. Furthermore, it is demonstrated that all the signals of the resulting system are finite-time stable and the tracking error converges to a neighborhood of origin in finite time without violating the output constraint. Finally, the simulation results show that the integration of squared error results, the integral of time and absolute error results as well as the integration of absolute value error results of the proposed scheme is smaller than the tested scheme by 0.3458 [Formula: see text], 22.2977 [Formula: see text], and 2.2513 [Formula: see text], respectively, when the time delays are considered. It further elucidates the availability and superiority of the developed method.

“…The previous literatures almost all discussed the control of single PMSM [9,10], and rarely discussed the control of two PMSMs, because the coupling effect between two motors should be considered at this time. In addition, some scholars use interval matrix to control CPMSMs system [6], but the effect of its controller may not meet the control requirements.…”

Aiming at the disturbance mismatch in the coupled permanent magnet synchronous motors(CPMSMs) system, a new design method of active disturbance rejection controller(ADRC) is proposed in this paper. In order to eliminate the coupling tension between motors, the control law is designed in two stages, so that the disturbance and control input appear in the same channel, and then the ADRC is designed to realize the control goal by using the control input. The proposed method is more universal than the previous methods, and the parameter tuning is easier. At the same time, it simplifies the design steps of the controller and reduces the requirements of the control system.
