A Pro-Active Resolver Model to Cope with Parameter Variability in the Manufacturing Chain

In this paper a linearized model for Pancake resolvers is developed with the aim of compensating deviations on manufacturing inputs through computed corrections on the production controllable variables, mainly winding parameters. This model follows a two-step strategy where at the first step an accurate model computes the resolver nominal conditions and at a second step a linearized model based on production controllable variables computes the corrections on these controllable variables in order to compensate small deviations on the nominal conditions due to processes variability in the manufacturing. This model had been simulated and experimentally tested in a Siemens resolver manufacturing plant. The tests done proved the efficiency of the developed model and its usefulness in stabilizing the product specifications in a dynamic environment with high variability of manufacturing processes.
