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].
