Dynamical Synchronous Control of Chaos Motor Systems in Complex Network with Small-World Topology
Identical permanent magnet synchronous motor (PMSM) systems, with chaotic characteristics, are selected as nodes to construct a linearly coupled small-world dynamical network. The synchronous control for coupled PMSM network is studied. Synchronous condition of pinning control linearly coupled network is deducted, and the status equations of pinned network is presented to realize synchronous control of PMSM network. Controller is applied to adjust the direct- and quadrature-axis stator voltage. Simulation results show that complex dynamical network with the small-world model can be synchronous controlled to the equilibrium point via a few linear feedback controllers. In contrast with the nearest-neighbor coupled network, synchronous control of the motor network with the small-world topology is adjustable, highly efficient and low cost. The research results provide a important way for experimental study and the engineering design of motor network to improve synchronous control performance and lessen cost.
