Control Algorithm And Simulation Research Of Hydrostatic Transmission System On Generating System In Walking Machines

With the development of electric and electron technology, the electro-equipment need more and more electric power and generating system in walking machine is applied in industry wildly. The traditional supply measure of generating system is not economical to the civil affair and not enough flexible to the military affairs, so it is very important to completely solve those problem of traditional power supply in the walking machine .Basing on Modeling And Simulation Research Of Hydrostatic Transmission System On Generating System In Walking Machines, the research will supply a more reasonable and effective control algorithm for the generating system.In this dissertation, firstly analyze the characteristic of the generating system in walking machine. Because of the character of variable speed and variable load, it is very difficult to use the traditional PID control to achieve the constant speed. So aiming at the characters of this generating system, hereinafter four control methods are researched, such as NCD optimizing PID control, Fuzzy logic online optimizing PID control, Fuzzy logic and PID parallel control and Gain schedule PID base on Genetic algorithm. Using MATLAB/Simulink emulational experiment to get the control effect, then compare each of control methods to get the conclusion that the Gain schedule PID base on Genetic algorithm is the fittest control method to this system, can meet the need of the generating system in walking machine.
