The Preliminary Design Of The Real-time Control Of The Super-short-range Antimissile System

This thesis discuss the application of the embedded system in the super-short-range antimissile servo system. Derive the transmission function of the system, design the control strategy that combine impulse function with PID, and carry on emulate. Choose the suitable drive and control mechanism, design the correlative hardware interface, make up the simulate servo system preliminary. Write the software under the operating system of uC/OS-â…¡. Finish the preliminary design of the real-time control of the servo system basically. The majoy content as follows:(1) Design the control algorithmAccording to the characteristic of the super-short-range antimissile, design the control strategy that combine impulse function with PID, add superior pulse voltage when the start-up of the system in order to satisfy the rapid start, then take the PID control strategy.(2) Build the simulate servo systemThe simulate servo system choose the S3C44B0X as processor, enlarge the periphery circuit of the servo system platform, design the correlative hardware interface, finish the design of the hardware of the embedded system. And design the motor driver module, choose the suitable direct current servo motor, reducer and photoelectricity coder, make up the intact simulate servo system platform.(3) Design the control softwareFinish the software of the system which is writen under the real-time operating system of uC/OS-â…¡, including the communication task, the output of the PWM pulse task, the servo control task and the main program. Through the comprehensive debugging of the software and hardware, the global design meets the index request.
