“…The modeling of the linear synchronous machine follows several assumptions, such as magnetic hysteresis, Foucault currents, and saturation effects are negligible [23]. Also, the resistances are constant, the stator windings are positioned sinusoidal and the stator slots are not considered [11,18].…”

This paper synopsis a new solution for Permanent Magnets Linear Generator (PMLG) state estimation subject to bounded uncertainty. Therefore, a PMLG modeling method is presented based on an equivalent circuit, wherein a mathematical model of the generator adapted to wave energy conversion is established. Then, using the Linear Matrix Inequality (LMI) optimization and a Lyapunov function, this system's Sliding Mode Observer (SMO) design method is developed. Consequently, the proposed observer can give a robust state estimation. At last, numerical examples with and without uncertainty are included to exemplify the effectiveness and applicability of the suggested approaches.

“…The finite-time control tools can provide outstanding convergence and excellent robustness from the perspective of a time-optimized control scheme. Numerous effective methods based on finite-stability theory are devised to obtain the high convergence speed and the response of the PMSMs [27][28][29]. For example, a finite-time control approach is brought finite time to track the desired motor position [27].…”

“…To illustrate the dynamic response and immunity to the disturbance, a finite‐time controller is devised. It ensures that the system output tracks the demanded velocity signal for a finite period [28]. Several improved theorems based on finite‐time control are utilized to confirm the finite‐time stability [30].…”

This article presents a disturbance‐observer‐based adaptive finite‐time dynamic surface control scheme, capable of guaranteeing transient behavior for the PMSM with arbitrary asymmetric time‐varying output constraint and unmatched external disturbance. The major challenge of this paper is devising efficient strategies to tackle the nonsymmetric output restraints with arbitrary characteristics and unmatched external perturbation for the system under the finite‐time backstepping framework. Given this, a nonlinear transformation function is adopted to coordinate from the output‐constrained dynamic model to an uncontained one, and a finite‐time disturbance observer is introduced to evaluate the unmatched external perturbation. Then, a dynamic surface control approach having adaptive properties for PMSM is conceived by combing a neural network to evaluate the nonlinear functions and a first‐order filter to handle the “explosion of complexity.” Additionally, it is proved that the signals in the closed‐loop system can narrow down to a bounded region and the tracking error can merge in a limited time to tiny vicinity of zero by employing a fast finite‐time stability principle. Eventually, simulation cases and contrast results reveal the tracking performance and immunity to the disturbance of the devised controller.

“…The low pass filter is used to get the average value, and the dynamic response speed of the system is reduced. [7][8][9][10][11][12] The current balance control method can maintain the input current equal to the output current in the converter, so that the current of capacity is close to zero, the dynamic response is fast and DC voltage fluctuation is small, but it is difficult to achieve. 3,13,14 The direct power control strategy is proposed with the instantaneous reactive power theory applied to dual-PWM converter.…”

The common dual-pulse-width-modulation converter adopts the independent method to control the rectifier and inverter, which has the defects including direct current voltage fluctuation, slow system response and so on. A coordinate strategy of dual-pulse-width modulation based on direct power control with load power feed-forward is proposed in this paper. The fixed switching frequency method with space vector pulse width modulation is provided to overcome the instability of power devices, caused by the hysteresis comparators in the conventional direct power control. With the analysis on the dynamic performance of load power feed-forward coordination, the principle of load power feed-forward is introduced to control the dual-pulse-width-modulation converter. According to the state variable of the alternating current motor, the load power is estimated to construct the feed-forward channel. The experimental results show that the proposed coordinate control method has rapid response, direct current bus voltage fluctuation minimization, lower capacity and unit power factor.
