Research On Excitation Control Strategy Of Hybrid Excitation Permanent Magnet Synchronous Generator

Hybrid excitation permanent magnet synchronous generator that is the generatorof a new structure and small independent power supply system has a broad applicationprospects. At home and abroad on the body, its structure and properties of hybridexcitation permanent magnet synchronous generator has done a lot of work, butsystematically expounded the generator control principles and methods of literature isnot much. To ensure good system performance controller must be adjuste d accordingly.Intelligent control strategy with a mathematical model that does not depend on theobject and robustness, control system parameters and nonlinear uncertainties can beovercome, so that static and dynamic performance and anti-jamming measures toachieve Optimal.First paper detailed analysis basic structure, the working principle of hybridexcitation synchronous generator, load characteristics and operating characteristics.And on this basis, combined with assumptions, potential equation and the fluxequation of this new hybrid excitation synchronous generator in the dq rotatingcoordinate system is derived, the corresponding mathematical model and simpleequivalent circuit for the intelligent control strategy the design of the study, theexcitation control system provides the necessary theoretical basis.Followed by different intelligent control strategies for hybrid excitationpermanent magnet synchronous generator have been studied. Since the specialstructure of this study motors, parameter design complexity, and the motor’s internalelectromagnetic coupling are more difficult to achieve precise calculation, and thuscan not get a precise mathematical model. Based on this, the intelligent control ofthree different methods used in hybrid excitation permanent magnet synchronousgenerator excitation control system. They are fuzzy control, self-tuning fuzzy PIDcontrol and fuzzy neural network control. The first analysis of a variety of intelligentcontrol method control theory, and then the special structure of the hybrid excitationpermanent magnet synchronous generator, designed fuzzy controller self-tuning fuzzycontroller, fuzzy neural network controller. The hybrid excitation permanent magnetsynchronous motor control system using Matlab simulation model, three differentcontrol methods for from zero boost experimental and anti-jamming capabilityexperimental results were compared. Simulation results show that the design of hybrid excitation permanent magnet synchronous generator three different control methodshas good static and dynamic performance and anti-jamming capability, can be wellapplied to actual industrial control systems.
