Direct torque control based speed control of permanent magnet synchronous motor using nonlinear inflexible sliding mode technique [articol]

Abstract

Now a days Permanent Magnet synchronous motors are widely used in industrial applications. In a reconfigurable assembling condition, control framework design needs creative ways to deal with face the fast changes in hardware and software modules. The control framework ought to have the capacity to naturally tune its parameters to upgrade machine exhibitions and powerfully adjust to various control destinations while preserving in the meantime stability and toughness properties. In this work, a powerful control framework for permanent magnet synchronous motors (PMSMs), together with an online self-tuning Nonlinear Inflexible Sliding Mode (NISM) technique, is exhibited. Mainly, a robust discrete-time Variable Structure Control (VSC) has been composed. An NISM approach has been then executed on a digital signal processor (DSP) to discover the VSC parameter set which limits a particular target work each time a different speed reference is given. The performance of Nonlinear Inflexible Sliding Mode methods was validated through simulation results. The design, analysis, and simulation of the proposed method are done using MATLAB Simulink environment. The simulation exhibitions alongside test consequences of the PMSM drive are considered for beginning, consistent state condition, speed inversion, and load perturbation. The test results demonstrate that the driving framework has an excellent unique reaction especially concerning torque swell and speed reaction.
