Abstract : Induction Motors have been used as the workhorse
in the industry for a long time due to its easy build, high
robustness, and generally satisfactory efficiency. However, they
are significantly more difficult to control than DC motors. One
of the problems which might cause unsuccessful attempts for
designing a proper controller would be the time varying nature
of parameters and variables which might be changed while
working with the motion systems. One of the best suggested
solutions to solve this problem would be the use of Sliding Mode
Control (SMC). This paper presents the design of a new
controller for a vector control induction motor drive that
employs an outer loop speed controller using SMC. Several tests
were performed to evaluate the performance of the new
controller method, and two other sliding mode controller
techniques. From the comparative simulation results, one can
conclude that the new controller law provides high performance
dynamic characteristics and is robust with regard to plant
