“…For the frequency conversion speed regulation system of medium and high voltage and high-power PMSM (permanent magnet synchronous motor), a multi-mode modulation strategy is usually adopted to solve the defects of a single modulation strategy [24]. However, the smooth switching between different modulation strategies is critical for multimode modulation strategies.…”

In addressing the issue of high common-mode voltage amplitude and output waveform distortion caused by low switching frequency in medium and high-voltage high-power variable frequency speed control systems, the neutral-point clamped three-level inverter is taken as the research object, from the perspective of switching sequence design, a detailed analysis of the switching sequence design method to mitigate the common-mode voltage amplitude, minimize the switching times and enhance output waveform quality. An improved synchronous space vector pulse width modulation strategy is proposed. Secondly, the improved strategy is applied to the closed-loop control of permanent magnet synchronous motor. Aiming at the defects of single modulation mode, the multi-mode modulation strategy based on the improved strategy is proposed, and the smooth switching of modulation mode is realized by limiting the switching phase. The compensation schemes for angular deviation under synchronous modulation and angular delay under digital control are studied to improve the system's stability. Finally, a simulation and experimental platform is built to verify the correctness and effectiveness of the improved and multi-mode modulation strategies.INDEX TERMS common-mode voltage, closed-loop control, multi-mode modulation, permanent magnet synchronous motor, space vector pulse width modulation, three-level inverter

“…Important control strategies for induction motors are available in scientific literature such as field orientation control, direct torque control, model predictive control, sliding mode control, and intelligent control techniques. However, the dependency on model parameters, complexity, and highly demanding computational effort of intelligent techniques causes a gap that needs to be covered with new efficient strategies including the effect of power electronic drives [3]. A strategy for rotor position control of induction motors based on field-oriented control, incorporating a scheme that utilizes neural networks to address time-varying dynamics and a nonlinear structure is presented in [4].…”

In this paper, we introduce an efficient adaptive algorithm based on B-spline neural networks for trajectory tracking of angular position for industrial induction motors. This strategy is developed in a twoaxis reference frame and the regulation algorithm is based on four main stages: a) flux observer; b) internal control loop; c) determination of required electrical currents and; d) calculation of the three-phase input voltages. The strategy considers an algebraic regulation scheme based on the model. The control parameters are tuning online to attain the best dynamic behavior, besides, the proposed adaptive controller is subject to non-modeled components as an 84-pulse voltage source converter included in this study. These two aspects make the main contribution of this article. The proposed high-performance strategy for trajectory tracking of angular position is demonstrated by simulation results using the parameters of two induction motors of 500 hp and 50 hp, respectively.
