Hybrid Nonlinear State-Space Modeling Approach for a Dual Armature Generator

A novel hybrid state space modeling approach for a dual armature generator is presented. The model uses finite element analysis to obtain the rotor angle-dependent parameters, namely flux linkage, stator inductances and cogging torque, which are then incorporated into dynamic equations of using Fourier representations physical parameters as function angle. proposed addresses many limitations classical approach, analytical expressions linkage based on significant simplifications. verified experimentally by simulating dynamics three-phase permanent magnet generator. Predictions new compared both experimental measurements predictions classic approach. It shown that simulates demonstration machine within 7% peak error in current provides 13% improvement prediction velocity with model.
