Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - From the perspective of further reducing the system cost and realizing high-performance vector control, the book takes the surface mounted PMSM as the research object and studies the phase current sampling reconstruction technology and sensorless control technology. Aiming at the chaotic control problem with uncertain parameters of the PMSM operating system, this paper designs an adaptive sliding mode chaotic control algorithm based on the adaptive control theory. The uncertain parameter model of the PMSM system is established. The parameter uncertainty defines the tracking error of each state and the error of its system parameters. Based on the error system, an adaptive law with unknown system parameters and state variables is constructed, and the sliding mode arrival condition based on the LMI algorithm is introduced to solve and prove the stability of the control system. Finally, the simulation experiment proves the effectiveness and robustness of the adaptive sliding mode controller based on the LMI algorithm designed for the parameter uncertainty of the PMSM operating system.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - With the continuous innovation of power electronics and automation control technology, China's industrial modernization process has been significantly accelerated, and more people can experience the improvement of modern industrial products on the quality of life. In order to realize the sustainable development of society and economy in China, permanent magnet synchronous motors are widely used in various fields of social production and life, such as industrial automation, home appliances, transportation, aerospace and other occasions. The State Council has set a clear target: by 2030, China's carbon emissions per unit of GDP should be cut by more than 65% compared with 2005, so as to achieve the ambitious goal of 'carbon peak'. In order to achieve the grand goal of 'carbon peak' as soon as possible, at present, major enterprises in China are actively promoting the upgrading of key energy-consuming equipment such as motors, giving priority to the adoption of high-efficiency and energy-saving motors, and accelerating the elimination of backward and inefficient motors that do not meet the current national energy efficiency standards.…
