Control Systems and Robotics (CSR) Reasearch Group

Introduction

The Control Systems and Robotics (CSR) research group at Department of Electrical Engineering, NUST College of Electrical and Mechanical Engineering focuses on research activities related to design, analysis, simulation and implementation of closed loop control of dynamical systems. The areas of interest are, but not limited to, linear control, nonlinear control, adaptive control, robust control, optimal control, digital control etc. Over the years, expertise in these areas have been developed through teaching relevant courses, conducting undergraduate projects and postgraduate research theses.
