International Journal of Computer Sciences and Engineering (A UGC Approved and indexed with DOI, ICI and Approved, DPI Digital Library) is one of the leading and growing open access, peer-reviewed, monthly, and scientific research journal for scientists, engineers, research scholars, and academicians, which gains a foothold in Asia and opens to the world, aims to publish original, theoretical and practical advances in Computer Science,Information Technology, Engineering (Software, Mechanical, Civil, Electronics & Electrical), and all interdisciplinary streams of Computing Sciences. It intends to disseminate original, scientific, theoretical or applied research in the field of Computer Sciences and allied fields. It provides a platform for publishing results and research with a strong empirical component. It aims to bridge the significant gap between research and practice by promoting the publication of original, novel, industry-relevant research.

A robust sensorless control of doubly-fed induction motor (DFIM) is proposed in this paper. The stator of the DFIM is connected to the grid and the rotor is fed via controlled voltage source. Since the speed or flux measurement is not used, the sensorless control is achieved by using multirate output feedback (MROF)-based output feedback technique. The robustness towards parametric variations and matched disturbances is achieved by using MROF-based sliding mode control (SMC). The linear equations of doubly-fed induction motor are utilised for application of MROF and the state reference commands are computed from torque and speed reference commands separately. The proposed MROF-SMC controller is shown to be tracking given torque and speed commands.
