Research On Control Arithmetic And Implementation Of CPT System Based On Embeded Technology

Contactless Power Transfer(CPT) is a novel power transfer technique, which overcomes many disadvantages of traditional power transfer technique and bring giant social benefits. At present, many research institutes are doing theory studying around the world. The main purpose of this paper is to estimate how to guide the CPT system transferring power at it's largest power rate.Embeded technology is resulted from combination of computer technology, semi-conductor technology, communication technology and micro-electric technology, it will be an important direction in the future technology development. Embeded control system applies embedded technology and control technology, which will paly an important role in many engineering fieds.This paper is based on a foundation project from science council of Chongqing municipal government, which is to establish a software platform for CPT control system under a hardware platform based on S3C2410. After analyzing some traditional operating system, Embeded Linux is used.To meet the system's real-time requirement, this paper analysis control system's real-time requirments and then conclude the main factors which would influence the real-time characters of standard Linux. An improved way of adopting RT_Linux is proposed. Bused on analyzing RT_Linux's principle, it's kernel and replanting are studied.Aiming at the design of CPT system's intelligent controller, traditional PID control and intelligent PID control are introduced as foundation of intelligent control method. Intelligent PID is used in CPT control to accomplish it's controller.A simulating model is constructed under Simulink, system controller based on traditional PID control and intelligent PID control have been simulated respectively. The intelligent PID control algorithm has been validated by simulation result.
