| Abstract | Linearisation of a nonlinear system allows a simple fixed controller to be applied for the control of the linearised system. In this paper, a new method of linearisation of permanent magnet (PM) synchronous machine model is proposed. The proposed method, removes the dominant quadratic nonlinearity of the model as well as higher order terms involving the input in the system. The proposed technique does not introduce any singularities in the system unlike the case conventional feedback linearization techniques. To illustrate the proposed technique, a numerical model, which is based on the actual parameters of a PM machine, is linearised. Also, a MATLAB simulation of the dynamic equations of the machine is carried out. Simulation results show that the proposed technique effectively linearises the machine model. Also, the linearised system exhibits a stable open loop response unlike the open loop system response before linearization. The proposed technique can also be applied to linearise induction motor and wound rotor synchronous machine models. |

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.
