| Abstract |
This paper deals with vector control strategies of very high speed permanent magnet synchronousmotors. It proposes a non-linear method, the interconnection and damping assignment - passivitybased control (IDA-PBC), which development uses the system energy equation to describe itsbehavior. This equation will be used in order to find a new function called the desired function. Theidea is to impose on the system variables a well-defined trajectory until a point of equilibriumcorresponding to the minimal energy. Then, a damping injection is realized in order to obtain theasymptotic stability. Simulations are used to set the controller gains and to test the sensitivity of theproposed method to parametric variations, especially regarding to the magnetic flux. This last studyhas showed us the limitation of the IDA-PBC to reject modelling errors. To improve passivity basedcontrol method, we propose a new control strategy using an hybrid model, designed to compensatethe parametric errors. |
