In this paper, the flight control system for a small size unmanned helicopter is discussed. The system is mainly used as a platform for the research of autonomous flight controller. So the modularity and expansibility is preferred. Firstly, the hardware of the system are designed based on DSP and FPGA. Then the function modules of FPGA is provided, which are designed to ensure the system's expansibility...
According to the requirement of a wild-radio's power supply, a 25V/5A Solar-Pull-Push-DC-Power Supply with high precision and quickly dynamic response has been developed. The CPU is TMS320LF2407A, the main circuit is pull-push DC/DC converter, and PWM control method has been used too. The accuracy and the dynamic response have been greatly improved because of the use of a digital PID regulator. So...
