This paper presents a new seonsorless vector control system for high performance induction motor drives fed by a matrix
converter with non-linearity 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
disturbance 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 response at the low speed operation. Experimental results are
shown to illustrate the performance of the proposed system.
