Abstract

The invention relates to a fuzzy finite time optimal synchronous control method of a fractional order permanent magnet synchronous generator, and belongs to the technical field of generators. A synchronous model between the fractional order driving permanent magnet synchronous generator and the fractional order driven permanent magnet synchronous generator with capacitance-resistance coupling is established. Rich dynamic behaviors including chaotic oscillation of the system are fully revealed through dynamic analysis, and stability and non-stability boundaries are given through a design numerical method. And then, under the framework of a fractional order backstepping control theory, a fuzzy finite time optimal synchronization control scheme fusing the hierarchical type-2 fuzzy neural network, a finite time command filter and a finite time preset performance function is provided. Stability analysis proves that all signals of the closed-loop system are bounded under the condition that the cost function is minimum. Finally, a numerical simulation result verifies the feasibility and superiority of the method.

Description

technical field [0001] The invention belongs to the technical field of generators, and relates to a fuzzy finite-time optimal synchronization control method for a fractional-order permanent magnet synchronous generator. Background technique [0002] The permanent magnet synchronous generator is one of the most important electrical equipment. It can convert wind energy into mechanical work, and drive the magnetic rotor to rotate through mechanical work to output alternating current. Currently, it is widely used in high-speed power generation, renewable energy power generation, and wind power generation. Permanent magnet synchronous generators in wind power stations generally work in harsh environments, and fluctuations caused by local wind speed, generator temperature, magnetic field, friction and workload are inevitable. These fluctuations may cause many nonlinear dynamic phenomena such as chaotic oscillation, multi-stability, and bifurcation of permanent magnet synchronous...
