This paper presents a new method to improve sensorless performance of matrix converter drives using PQR power transformation. The
non-linearity of matrix converter drives such as commutation delay, turn-on and turn-off time of switching device, and on-state
switching device voltage drop is modelled using PQR transformation and compensated using a reference current control scheme. To
eliminate the input current distortion due to the input voltage unbalance, a simple method using PQR transformation is also proposed.
The proposed compensation method is applied for high performance induction motor drives using a 3 kW matrix converter system
without a speed sensor. Experimental results are shown to illustrate the feasibility of the proposed strategy.
