“…IPMSM is a complicated system of high-nonlinearities, strong-coupling and multi-variables, and its parameters are very sensitive to environment. In order to achieve high control performance of IPMSM, such as fast response, high precision, and strong anti-disturbance capacity, various control strategies are proposed including proportional integral (PI) control [4], [5], [6], [7], [8], neural network (NN) control [9], [10], [11], [12], [13], [14], fuzzy control [15], [16], [17], [3], [18], sliding mode control [19], [20], [21], [22], [23], predictive control [24], [25], [26], [27], dynamic surface control(DSC) [10], [28], [29], [30], [13] and extended-state-observer-based control [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], etc. Specifically, in [3], a discrete-time fuzzy position tracking controller is designed via backstepping approach to overcome the problem of coupling nonlinearity in the IPMSM drive system.…”

In this paper, an anti-disturbance output feedback dynamic surface control (DSC) method is proposed for the position tracking of interior permanent magnet synchronous motor subject to unknown nonlinearities and time-varying disturbances. Specifically, a nonlinear extended-state-observer (NLESO) based on exponential functions is designed to estimate the total disturbance composed of system uncertainties and external disturbances. Then, by compensating for the total disturbance via the NLESO, an anti-disturbance output feedback law is designed based on the DSC approach. The salient features of the proposed approach is twofold. First, the total uncertainty including internal and external disturbances can be accurately estimated by an NLESO in real time. Second, the desired anti-disturbance performance of the servo control system can be achieved regardless of the position measurement only. The stability of the closed-loop control system is proved by using the cascade theory and input-to-state stability theory. Both simulation and experiment results are conducted to illustrate the effectiveness of the proposed control method.

“…Although the majority of controllers in industry are designed as PID or PI type, the practical applicability of the FOPD controller has been verified by existing studies [27–30]. For example, in [27], an FOPD controller was designed for a real‐time hard‐disk‐drive servo system, which successfully improved the system track‐following control performance.…”

“…The application of an FOPD controller on a horsepower dynamometer was presented in [28], where the practical system achieved favourable robustness and transient performance. Wang and Pi [29] show that the designed FOPD controller outperforms traditional optimal controllers when both are applied to a permanent magnet synchronous motor. Another FOPD controller used in active vibration suppression for aeroplane wings, could significantly improve the vibration suppression effect in smart beams [30].…”

An improved robust stability surface analysis method is proposed in this study for fractional‐order time‐delay systems. Through the stabilisation process, a synthesised fractional‐order PD controller can be designed with guaranteed robustness specifications. Firstly, the specification for improved robustness requirements is proposed. In order to find selectable robust controller design parameter combinations for the controlled system, stability region is discussed based on the stability boundary locus, and the robust stability surface is derived straight after. Secondly, the selectable parameter combinations are checked to find the one that best fulfils all the proposed robustness specifications. Finally, numerical simulations are given to demonstrate the effectiveness and flexibility of the presented control algorithm.

This study mainly investigates the current and speed control strategies of a doubly-fed induction generator (DFIG), which is applied to a tidal stream turbine (TST). Indeed, DFIG using integer-order PI (IOPI) controller has been widely proposed in the applications with a similar system, especially in wind energy conversion system (WECS). However, these conventional controllers cannot deal with the problems caused by the parameter variations satisfactorily under complex and harsh operation conditions, and may even deteriorate the performance. As a result, a fractional-order PI (FOPI) controller is considered to improve the efficiency and performance of DFIG-based TST in this paper. The FOPI controller, developed from the traditional IOPI controller and the fractional calculus theory, has a lot of prominent merits in many aspects, such as robustness, stability, and dynamic performance. In this paper, the proposed control strategies are embedded into the whole TST model which contains the tidal stream turbine, and the generator. The obtained simulation results demonstrate the prominent effectiveness and advantages of the proposed strategies compared with the conventional IOPI controller in terms of overshoot, static error, adjustment time, and robustness. It implies that FOPI controller could be a good candidate in TST applications.
