Abstract

This paper presents an optimal control of Permanent Magnet Linear Synchronous Motor (PMLSM) using linear quadratic regulator. The linear quadratic regulator is employed by linearization of motor model to obtain the optimal state feedback gain matrix. Optimal Control Methodology facilitates to design a control system, to meet the performance objectives with the smallest control energy i.e. the energy associated with the generation of control inputs. In pole placement techniques, Trial and Error method is adopted to find the pole location for desired performance of the system, whereas the optimal control methods directly formulate the desired performance of the control system The PMLSM drive is simulated by taking various Q and R matrices in order to eliminate the steady state error and enhance the dynamic performance of various speed profiles.
