Abstract | In this document a new proposal of speed vector control of induction motors based on robust adaptive VSC (variable structure control) law and its experimental validation are presented. This control scheme uses the SVPWM (space vector pulse width modulation) instead of the traditional current hysteresis comparator, because the space vector modulator eliminates the instability risk when the motor works with large loads and provides best quality of the stator currents, maintaining the main characteristics of the original adaptive VSC algorithm: fast response and good rejection to uncertainties and measurement noises. This algorithm has an adaptive sliding gain that reduces the chattering phenomenon that usually appears in the traditional control schemes. Thus, this regulator is compared with the non adaptive SVPWM-VSC and the PI (proportional integral) controller designed in the frequency domain, in order to prove the good performance of the proposed controller. The controllers have been tested using various simulation and real experiments, with and without load, and in the proposed case, taking into account the parameter uncertainties and measurement noise in the loop signal, in the rotor speed and in the stator current. This work shows that the robust adaptive VSC regulator is a good and usable controller, in both adverse conditions and suitable conditions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
