Research on Turn Ratio of Magnetic Valve Type Controlled Reactor Based on Bifurcation Theory

Magnetic valve type controlled reactor (MVCR) is the electrical equipment which shows some strongly nonlinear properties when working and its performance is influenced by its turn ratio. Some irregular phenomenon, for example, the mutation of ultimate dynamic state, the uncertain electromagnetic or mechanical noise, may occur under the condition of the improper value of turn ratio. In order to study the nonlinear behavior, by using the fixed period discrete mapping modeling method, the discrete mapping model of MVCR is established, the performance of the MVCR is analyzed based on the bifurcation theory for nonlinear dynamics and the reasonable value range of turn ratio is obtained. Simulation confirms that the result above is rational. The conclusion in the paper may provide a certain theoretical basis for the designing of controllable reactor in actual engineering.
