The Performance Research of Speed Sensorless Induction
Motor System Controlled by the IDA—PBC
ABSTRACT
Recently,the theory of port—controlled Hamiltonian system based on the energy shaping has ing more popular in the high performance control of AC motors.
Based on the theory of port—controlled Hamiltonian system,the interconnection and damping assignment(IDA—PBC)based on passivity-based control method is used tO design nonlinear controller for the induction motor and permanent synchronous motor in this main characteristic of the method is that the controlled system can be transformed into a port·controlled Hamiltonian system, and according to the feedback stable principle of the PCH model,the voltage controller is then designed and implemented to make the whole system operate stably at the desired equilibrium points.
Firstly,the performance of induction motor systems controlled by the three IDA-PBC methods has been summarized pared with each ,the high performance scheme of induction motor controlled by the IDA-PBC method iS established,then,a PI rotor resistance observer iS designed and a model reference adaptive speed sensorless is implemented,and then,using
the IDA—PBC control,the IM vector control system implements its stable operation
with speed sensorless.
Based on the abovementioned researches,a new nonlinear controller iS designed for the PMSM based on the PCH ,a sliding mode observer is designed
