Passive control of Permanent Magnet Synchronous Motor chaotic system based on state observer
Journal of Zhejiang University Science, 2006Co-Authors: Qi Donglian, Wang Qiao-yiAbstract:Passive system theory was applied to propose a new passive control method with nonlinear observer of the Permanent Magnet Synchronous Motor chaotic system. Through constructing a Lyapunov function, the subsystem of the Permanent Magnet Synchronous Motor chaotic system could be proved to be globally stable at the equilibrium point. Then a controller with smooth state feedback is designed so that the Permanent Magnet Synchronous Motor chaotic system can be equivalent to a passive system. To get the state variables of the controller, the nonlinear observer is also studied. It is found that the outputs of the nonlinear observer can approximate the state variables of the Permanent Magnet Synchronous Motor chaotic system if the system’s nonlinear function is a globally Lipschitz function. Simulation results showed that the equivalent passive system of Permanent Magnet Synchronous Motor chaotic system could be globally asymptotically stabilized by smooth state feedback in the observed parameter convergence condition area.

Passive control of Permanent Magnet Synchronous Motor chaotic systems
Journal of Zhejiang University Science, 2005Co-Authors: Qi Donglian, Wang Jia-jun, Zhao Guang-zhouAbstract:Permanent Magnet Synchronous Motor model can exhibit a variety of chaotic phenomena under some choices of system parameters and external input. Based on the property of passive system, the essential conditions were studied, by which Permanent Magnet Synchronous Motor chaotic system could be equivalent to passive system. Using Lyapunov stability theory, the convergence condition deciding the system’s characters was discussed. In the convergence condition area, the equivalent passive system could be globally asymptotically stabilized by smooth state feedback.

sliding mode synchronization control method of double permanent magnet Synchronous Motor chaos system
2014Co-Authors: Chen Qiang, Zhai Shuangpo, Zhan QingAbstract:Disclosed is a sliding-mode synchronization control method of a double-permanent-magnet Synchronous Motor chaos system. The sliding-mode synchronization control method includes: establishing a chaos model of a permanent magnet Synchronous Motor system as shown in the form, and initializing system state and relevant control parameters; at each sampling instant, calculating synchronization errors, sliding model surfaces and a first-order derivative of the permanent magnetic Synchronous Motor chaos system; designing a robust controller by adopting an active sliding-mode control method and finally realizing quick synchronization of the chaos state of the double-permanent-magnet Synchronous Motor chaos system with two different initial conditions and uncertain parameters.

A Two-Speed Salient-Pole Synchronous Motor
Transactions of The American Institute of Electrical Engineers, 2020Co-Authors: Robert W. WiesemanAbstract:The design features and performance characteristics of salient-pole Synchronous Motors are well known and have been thoroughly covered in the technical press. The Synchronous Motor has been handicapped in the past because it is inherently a singlespeed machine, and a change in speed could be obtained only by a change in the frequency of the power supply. Changing the frequency, however, is not practical in most applications. The special pole described in this paper which allows two-speed operation of a Synchronous Motor to be obtained at high efficiency is a new feature2. The same principle applied to a generator enables two frequencies to be obtained at the sgame speed or the same frequency at two different speeds. All that is necessary to change the speed (or frequency) is a pole-changing switch for the stator winding and a reversing switch for the rotor winding. A 5000/2500-h. p., 600/300-rev. per min., two-speed Synchronous Motor was built without having first constructed a model of any kind. This Motor proved to be entirely satisfactory and its characteristics obtained by test aggreed very closely with the calculated characteristics. At either speed the two-speed Synchronous Motor functions exactly as the ordinary Synchronous Motor. There is nothing special or complicated about its construction, it does not require any more attention than the ordinary Synchronous Motor, and its expense of maintenance is just the same.
