Abstract:

In order to improve the performance and efficiency of the braking system for unmanned aerial vehicle, this paper design a dual-redundancy electric braking system. An analysis is given for the structure and features of the system,specially describing the key technique of unmanned aerial vehicle that is the design of electric actuator and brake-control box in detail. The control core of 28V low voltage brake drive controller is designed by DSP + CPLD , the hardware in the loop simulation platform show that the braking pressure is stable and balanced, the system is efficient and reliable, the control performance can meet the requirements of the electrical brake system.
