| This thesis is based on guided transformation of one type rocket, ues electromotor roll isolation and TV guidance technology, to design the control system of the guided rocket.The thesis describes design requirements of the control system, to design the overall control system of the guided rocket. In the control strategy, use PID control; in control loop, use the three-channel loop to design the control system. According to the basic functions and performance requirements of the control system, use TI's TMS320F2806 chip DSP as main controller, which abundant resources complete the hardware and software of the control system. The hardware design includes external DSP circuit, functional module interface circuit and PWM power amplifier. In DSP software-ccs environment, use the C language to program, software design mainly contains the overall process control system, composed of AD sampling program, serial communication program,PWM output program etc., in order to achieve rocket self check, program-controlled flight, guidance flight. By MATLAB software, make mathematical modeling for the pitch, yow and roll three channels, to optimize the PID control parameters.Finally, test the functional of control circuit board, and debug the guided rocket control system. The results show that guided rocket system design is correct, reasonable, well stability and reliability, and achieves better control effect. |
