Analysis And Control Method Of Neutral Stability

Neutral delay system is a special system with time delay, it can accurately reflect thechange rules, reveal the essence of things. So neutral delay system is often used todescribe the actual problems, such as, population ecology system, distribution networkincluding dissipation transmission line, heat exchange, circuit network, transverse cutting,turbo jet engine system, continuous sensing heating of small moving objects etc.. Thisthesis studies on the following problems in the neutral system background:First of all, take certain neutral systems and uncertain neutral system as the researchobject, to study the stability of neutral systems, to gives the stability criteria by Lyapunovstability theory, and the criteria is given in the form of LMI, it can be simulated byMatlab toolbox of LMI, and can be simulated by Matlab toolbox of Simulink, verify thethe effectiveness of the algorithm.Secondly, take linear uncertain neutral system as the research object, design patternof a neutral observer of the system is given, and controller is designed through theobserver, finally the system is controlled.Finally, take uncertain time-varying and time-delay neutral system as the researchobject, the output feedback observer is designed, and design the corresponding controllerbased on state feedback observer, to control the neutral system.
