Research And Development Of An Advanced DC Driver

Today,autoeontro! systems have been widely used and developed in every walk of life,while DC speed regulation as the artery in the area of electric drive systems acts the main effect in modernization production.For a long time,DC motor has possesses the main role in the area of electric drive field because of its neatly adjust,easy method and smooth timing in wide rage,also,its control performance is very good.With the advancement of technology,people use computers to realize control system more often.In 21st century,digital adjuster has been widely used in various of industrial machine's speed regulations. With the price's decreace of electric and electrical component,and the greatly technic advancement ,its performance has been increasingly manifesting superiority when used in electromotor's speed regulation.Today,there are many models of all digital DC speed regulation devices in the world.The all digital driver represented by MNETORII bings leap of quality of DC speed regulation system.The thesis starts with the DC speed regulation principle of double closed loops,studies DC driver MNETORII of British CT company,analyzes its software and hardware partly.The thesis analyzes the hardware circuit diagrm in detail,acquires understand of peripheral equipment's function through the analysis of the its circuit and advanced ideas of design of digital controller in the world.The thesis partly studies hardware structure and software buildup of the microprocessor SAB 80C517A,compares the likeness and difference between it and MCS-51.Combined with hardware diagram and analysi of the software, the PID algorithmicc program is found and its flow chart is made ,then study is made.Based on all work,combined with pertinent information of control theory and the new arithmetic of the DC speed regulation.the paper advances adaptive control based on single neuron in the PID arithmetic of the speed loop.The whole system is simulated using the dynamic simulated tool SIMULINK of MATLAB6.1 software.The simulated result indicates,the adaptive PID controller based on single neuron has the ability of self-organization and self-study, greatly adapts the wide range of change ol the controled object's parameters,and the control traits change little.Therefore it has hign robustness and adaptive ability.
