Abstract


More Electric Aircraft Electric Brake System subsystem , electromechanical actuation instead of hydraulic actuation mechanism , instead of the analog to digital brake controller hydraulic control box , greatly improving the overall performance of the brake system . Papers based on the all-electric braking system works , a TMS320F240 the Electric Brake digital control system , and elaborated on its hardware and software design , and analysis of the test results . Paper first briefly expounded the basic principle of the slip rate of non-slip control strategy , the basic structure of the the electromechanical actuation institutions and the digital controller , electromechanical actuation mechanism of the core - Brushless DC motor works control methods. Aircraft braking process is a nonlinear time-varying system dynamics mathematical modeling of the braking process , the the nonlinear factors exist in the braking process and time-varying characteristics , and control the parameters of the target slip rate fuzzy self- tuning PID control algorithm , simulation results show that this control algorithm can greatly improve the performance of the brake system . Paper exhaustively expounded to TMS3320F240 core controller hardware , and full use of the DSP internal resources and supplemented by peripheral circuits speed detection circuit of current feedback , overcurrent protection, and serial communication functions , using GAL16V8D brushless DC motor rotor position signal logic signal processing , IR2130 as a central component of the three-phase full-bridge circuit to achieve efficient brushless DC motor drive . Loop control strategy in the control algorithm has been improved , and the traditional PID algorithm , which slip rate of the closed-loop parameters of fuzzy self-tuning PID algorithm , torque ring lost all pressed and loose with the different parameters of the PID algorithm , The current loop PI regulator algorithm . Experimental results show that the system has good dynamic performance , can quickly and accurately track the desired braking thrust . Electric Brake System aircraft semi- physical simulation model FBI reliable control system hardware design and programming work the brake short time , to achieve the control requirements of the braking system .
