Method for designing controller structure for field-oriented controlling induction machine i.e. synchronous machine, in power train i.e. hybrid drive train, of motor vehicle i.e. motor car, involves deriving dice to control machine

摘要

The method involves creating an objective function for determining an optimum efficiency of an induction machine i.e. synchronous machine (40). Non-linear mathematical optimization problems of the objective function are created using a mathematical model in nonlinear secondary conditions. An optimization algorithm is applied to the optimization problems, where the optimization algorithm is in a position to linearize the secondary conditions. Optimized control dice is derived to control the induction machine from the result of the optimization algorithm. Independent claims are also included for the following: (1) a method for controlling an induction machine under an application of a controller structure (2) a arrangement for driving an induction machine to perform a method for driving a polyphase machine.
