This paper presents a new sensorless vector control system for high performance induction motor drives fed by a matrix converter
with nonlinearity compensation and disturbance observer. The nonlinear voltage distortion that is caused by commutation delay
and on-state voltage drop in switching device is corrected by a new matrix converter modeling. The lumped disturbances such as
parameter variation and load disturbance of the system are estimated by the radial basis function network (RBFN). An adaptive
observer is also employed to bring better responses at the low speed operation. Experimental results are shown to illustrate the
performance of the proposed system.
