Fuzzy Control The Dc-stabilized Power Supply By Single Chip Micro-comupter

In order to improve the ability of the students in the university , we establish the laboratory of ship power-station . The ship power-station is composed of dc voltager-stabilized power supply, electric motor, generator, distributor and load . Because the DC voltager-stabilized power supply is made of simulate component, its hardware is very complex , and it has other shortcomings , and so on , base on these reasons , we put forward the research : fuzzy control the de-stabilized power supply by single chip micro-comupter.The control nuclear of this system is base on the single chip micro-comupter , and use the fuzzy control , transform the dc voltager-stabilzed power supply based on simulate component into a digital one . In this paper , it discussed the theory of three-phase half control ; design the fuzzy controler ; used the fuzzy control in this system . This paper also introduce the plan of hardware and software , including the three-phase circuit, protect circuit, trigger circuit, examine circuit and so on in detail . The paper explained the method of control and the thought of software . In regard to the disturb in this system , adopt corresponding methods to avoid it . This system got used to the trend of digital power in the international , used the single micro-computer fully , and improve the general use of the power . In the experiment I used the simulator of INSIGHT52-E and the MEDWIN of windows .The experiment is completed in the ship power station of institute of ship engine , because work of the laboratory is very busy , there are some disadvantages in this system should be improved .
