This paper describes load torque identification (LTI) issue in induction motors with uncertainty, using dynamic sliding mode control (DSMC). In DSMC the chattering is removed due to the integrator which is placed before the input control of the plant. However, in DSMC the augmented system is one dimension bigger than the actual system and then, the plant model should be completely known. To solve this problem, a new optimal observer suggested. The advantage of the proposed approach is to have the system controlled as well as its main task i.e. LTI. Moreover, another property of proposed approach isthat the upper bound of the uncertainty is not used in DSMC and observer, which is important in practical implementation. Simulation results are presented to demonstrate the approach
