“…Due to their vast application prospects, these kinds of motors are broadly used for operation in low and medium power applications. Furthermore, they are used in high-performance electric drives such as electric vehicles, robotics, aeronautical spaceframes, and machine tools [2,3]. However, the motor model is nonlinear and sensitive to many uncertainties inside and outside the speed control system during operation, making it difficult for the conventional PI control topology to convene the excessive performance control requirements of the system.…”

The permanent magnet synchronous motor (PMSM) is a highly efficient energy saving machine. Due to its simple structural characteristics, good heat radiation capability, and high efficiency, PMSMs are gradually replacing AC induction motors in many industrial applications. The PMSM has a nonlinear system and lies on parameters that differ over time with complex high-class dynamics. To achieve the excessive performance operation of a PMSM, it essentially needs a speed controller for providing accurate speed tracking, slight overshoot, and robust disturbance repulsion. Therefore, this article provides an overview of different robust control techniques for PMSMs and reviews the implementation of a speed controller. In view of the uncertainty factors, such as parameter perturbation and load disturbance, the H∞ robust control strategy is mainly reviewed based on the traditional control techniques, i.e., robust H∞ sliding mode controller (SMC), and H∞ robust current controller based on Hamilton–Jacobi Inequality (HJI) theory. Based on comparative analysis, this review simplifies the development trend of different control technologies used for a PMSM speed regulation system.

“…Em [20], é realizado um reprojeto digital por meio de LMIs de controladores PIs de tempo contínuo, considerando um atraso de transporte, sem incluir incertezas paramétricas no reprojeto. Um controlador de velocidade H ∞ robusto por modos deslizantes é proposto em [21], em que uma superfície de deslizamento baseada em LMIs é utilizada, mas com validação dos resultados apenas em simulações em tempo real, não incluindo resultados experimentais em sistema físico.…”

Este artigo trata do projeto e da validação experimental de controladores robustos aplicados à regulação de velocidade de motores síncronos de ímãs permanentes. O motor é descrito por um modelo politópico, considerando que os parâmetros elétricos e mecânicos podem variar dentro de intervalos limitados. As equações dinâmicas do motor para as correntes id, iq e para a velocidade wm são discretizadas incluindo o atraso de implementação digital e uma ação integral sobre o erro de rastreamento da referência. Desigualdades matriciais lineares são utilizadas para obter rapidamente, de forma offline, ganhos de controle por realimentação de estados para as duas malhas de controle de corrente e para a malha de velocidade, em uma estratégia de projeto que só demanda do projetista a escolha de dois parâmetros, limitados entre zero e um, que estabelecem uma região para alocação dos polos de malha fechada. Resultados experimentais para um motor comercial de 11 kW ilustram um bom rastreamento de correntes e uma boa regulação de velocidade. Estudos comparativos mostram desempenho dinâmico superior ao de controladores PIs da literatura, sem demandar aumento no número de sensores, permitindo também a redução do acoplamento cruzado entre os eixos direto e em quadratura.

“…By using a PMSM mathematical model, many prior scholars have designed various advanced controllers for the speed system of PMSM efficiently, examples of such algorithms include model predictive control [5], finite-time feedback control [6], adaptive control [7,8], and H-infinite control [9]. In this paper, we refer to control strategies of the above as the model-related control strategy.…”

This study proposes a novel model-free intelligent proportional-integral supertwisting nonlinear fractional-order sliding mode control (MF-iPI-ST-NLFOSMC) strategy for permanent magnet synchronous motor (PMSM) speed regulation system. First of all, a model independent intelligent proportional-integral (iPI) control strategy is adopted for the motor speed regulation system. Next, a novel model-free supertwisting nonlinear fractional-order sliding mode control (ST-NLFOSMC) strategy is constructed based on the ultralocal model of PMSM. Meanwhile, a linear extended state observer (LESO) is used to estimate the unknown terms of the ultralocal model. Then, this study presents the novel hybrid MF-iPI-ST-NLFOSMC strategy which integrates the model-free ST-NLFOSMC strategy, the model-free iPI control strategy, and the LESO. Moreover, the stability of the proposed hybrid MF-iPI-ST-NLFOSMC strategy is proved by the Lyapunov stability theorem and fractional-order theory. Finally, the simulations and comparison results verify that the hybrid MF-iPI-ST-NLFOSMC strategy proposed in this paper has better performance than the other model-free controllers in terms of the static characteristic, dynamic characteristic, and robustness.
