AN OPTIMISATION-BASED APPROACH FOR DESIGNING INDIRECT SENSORS APPLIED TO AN INDUCTION MOTOR

This article proposes an innovative strategy to the problem of non-linear estimation of states in an induction motor, (IM). This method allows the estimation of variables that are difficult to access or that are simply impossible to measure. The estimation is made possible by using indirect measures...

The estimation is made possible by using indirect measures, through the consideration of a dynamic model of the process and an estimation algorithm based on non-linear optimization.
