DONG, KE. Advanced Design Techniques in Linear Parameter Varying Control. (Under the direction of Associate Professor Fen Wu). To improve the analysis and control synthesis approach of linear fractional transformation (LFT) parameter-dependent systems, two types of non-quadratic Lyapunov function and switching control scheme are introduced and studied in this thesis. A gain-scheduled controller...

*MIC College of Technology, Kanchikacherla ,Vijayawada ______________________________________________________________________________________ Abstract: During the last decade a new control method called DTC (Direct torque control) has been developed for electrical machines with conventional PI controller. The conventional PI controller is slow in adapting to speed changes, load disturbances and...

Adaptive Control strategies helps to get desirable output for system with partial unknown dynamics or systems having unknown and unmodeled load variation. DC servo motors are useful to track rapid speed trajectory for various applications, particularly with need of high starting torque and low inertia. Model Reference Adaptive Control (MRAC) parameter data of results with Lyapunov stability MRA...

A nonlinear chattering-free sliding mode control method is designed to stabilize fractional chaotic systems with model uncertainties and external disturbances. The main feature of this controller is rapid convergence to equilibrium point, minimize chattering and resistance against uncertainties. The frequency distributed model is used to prove the stability of the controlled system based on dir...

The Controller Area Network (CAN) is a communication bus for message transaction in real-time environments. A real-time system typically consists of several classes of messages and a scheduler is responsible to allocate network resources to fulfill timing constraints. Given sufficient bandwidth, the static scheduling algorithms can meet the bounded time delay. However, due to the availability o...
