SENSOR-FAULT TOLERANT BASED GAIN SCHEDULING CONTROLLER FOR NETWORKED DC MOTOR SYSTEM
Journal Title: Elysium Journal of Engineering Research and Management - Year 2015, Vol 2, Issue 4
Abstract
This work is concerned with the controller design of NDCMS. A fuzzy gain scheduling controller has been designed to overcome the sensor faults and also to manage the network delay and packet dropouts. Fuzzy gain schedulers allow the controller producing the optimal control action at different operating points. An algorithm has been used to execute the off-line tuning in each of operating point, and a fuzzy sub-system performs a fine tuning. This approach uses fuzzy gain scheduler to determine appropriate gains based on the system’s operating conditions. Sliding-mode observer is used to find the rotor speed and unknown load torque for the networked system. To evaluate the feasibility and applicability of the sensor-fault-tolerant controller, numerical and experimental tests are carried out.
