Abstract Several industrial applications demand high performance speed functioning and require new control techniques so as to ensure a fast dynamic response. The present work investigates real time implementation and experimental sliding mode controlled (SMC) induction motor drives (IM). The strategy of sliding mode control is a powerful tool to ensure robustness. Nevertheless, the chattering phenomenon is a major disadvantage for non linear systems. For this purpose, two different types of analysis such as layer boundary methods are implemented in dSPACE 1104 controller board and compared between them in order to obtain the best method to reduce or eliminate chattering phenomenon. An experimental results using dSPACE 1104 based on TMS320F240 DSP are described in this work.
