Two approaches of adaptive SFC PMSM

Adaptive state feedback speed controller for permanent magnet synchronous motor. Comparison of different model reference implementations.

The model allows to select one of two adaptation mechanism and one of four implementations of reference model for Model-reference adaptive system (MRAS) approach.

To analyse the impact of the proper selection of reference model for adaptive PMSM drive based on MRAC approach, the following models ware validated:

• A: second-order system based on mathematical model,
• B: first-order system,
• C: signal processing based on [1],
• D: memory used to archive desired response based on [2].

The implemented adaptation mechanism are as follows:

• Widrow-Hoff rule [1],
• Adaptation Procedure for Optimization Algorithms [2].

Moreover, in the init callback of simulink model the current (In) can be limitted to present the behaviour of the adaptation mechanisms. Model predictive approach is used to a posteriori constraint introduction into control system [3].
