“…While this method provides models that are rooted in physical reality, it demands a strong background in physics and a comprehensive knowledge of the system’s dynamics. The derived models are often complex and require precise parameter tuning, making them suitable for well-understood systems where the governing equations are known [8] , [9] , [10] , [11] , [12] , [13] , [14] . On the other hand, machine learning techniques, particularly those involving data-driven approaches, offer an alternative route to model development.…”

“…Moreover, the large torque ripple can be effectively suppressed by torque control methods such as the direct instantaneous torque control or the torque-sharing function [12][13][14]. Thus, the EMA driven by the SRM (SDEMA) is used in some applications, such as the small and medium aircraft, unmanned aerial vehicle, and steering vane control system on the landing craft air cushion hovercraft [15][16][17][18].…”

“…Therefore, the application of these methods in the modelling of the SDEMA system has some limitations. In [15], the authors present a novel modelling method of SDEMA based on the Lagrange‐Maxwell equation. This method considers the electromechanical coupling effect and non‐linear factors including friction and backlash of SDEMA simultaneously.…”

“…However, this method cannot consider the iron loss of the SRM, power converter loss, and non‐linear factor of flexibility, which makes the improved mathematical model of SDEMA not complete and accurate enough. In this study, the modelling method in [15] is perfected and named integrated non‐linear modelling method, which adds the analysis of iron loss of the SRM, power converter loss, and non‐linear factor of flexibility. Moreover, the mathematical models of non‐linear factors are improved to express as energy models that can be easily integrated into the Lagrange‐Maxwell function.…”

“…Thus, EMA usually uses the structure of the rotating SRM coupling with the ball screw and gearbox. The EMA presented in [15] (SDEMA) also uses the rotating SRM as its servo motor. But the SDEMA removes the intermediate gearbox and couples the SRM rotor with the nut of the ball screw directly, which reduces the probability of mechanical jamming and improves the reliability [21][22][23].…”

This study proposes an integrated non-linear modelling method for an electromechanical actuation system directly driven by the switched reluctance motor (SDEMA). The mathematical model of the SDEMA system is established by energy analysis and calculation according to the proposed method, which omits the complex analysis of force or torque transmission in the cascade modelling method. By using the Lagrange-Maxwell equation and establishing the energy models of non-linear factors that include the friction, backlash, and flexibility, both the electromechanical coupling effects and the nonlinear factors of the SDEMA system are considered simultaneously in the proposed method. To verify the feasibility and effectiveness of the proposed method, three modelling methods of the SDEMA system are comparatively studied through the simulations and experiments. The results of the simulations and experiments indicate that the proposed integrative non-linear model can reflect the dynamic performance of the SDEMA system more accurately.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

A Switched Reluctance Motor Drive Controller Based on an FPGA Device with a Complex PID Regulator

This paper presents a proposal for a new type of regulator for switched reluctance motor (SRM) drives. The proposed regulator enables a significant extension of the rotational speed range and drive output power. This regulator is characterized by a complex structure, including two regulation modules: voltage and phase supply switch-on angle. The voltage module includes a proportional integral derivative (PID) voltage regulator. During its operation, the value of the phase supply switch-on angle and the width of the phase supply range are determined as a result of interpolation of the data previously determined in the simulation program. The other module contains the PID controller of the phase supply switch-on angle. The values of the angles included in the tables have been determined so as to ensure that the drive works with the greatest possible efficiency. The control method is determined based on the current operating parameters of the drive, i.e., torque and speed. The operation of the regulator was simulated in the MATLAB Simulink program. The regulator presented here was implemented in a field programmable gate array (FPGA). Tests of the regulator’s operation in the prototype system were carried out in the field of control of commutation angles.
