Optimal Positioning Coordination for Multiple Linear Switched Reluctance Machines

This paper proposes a coordinated positioning control network for three direct drive, linear switched reluctance machines. To obtain the optimized network control parameters, the distributed linear quadratic regulator is applied. Different communication topologies are studied for both the dynamic tracking and the coordination performance of the network. Experimental results demonstrate that an absolute static tracking precision of 20 μm can be achieved from the “cycle” communication topology and an absolute static coordination precision of 11 μm can be obtained from the “path” communication topology.
