【摘要】：以FPGA语音识别命令作为四旋翼的航拍遥控命令,将FPGA快速处理信息的能力与语音控制的简单、准确、灵活特点相结合。控制系统分为2部分,四旋翼飞行器利用单片机,采用模糊神经网络PID控制四旋翼螺旋桨的转速达到对机身的飞行高度和方向的控制;语音遥控命令利用FPGA,采用优化的隐马尔可夫模型完成对机身的飞行姿态的命令控制。经仿真验证语音控制四旋翼控制系统具有很强的实时性,能很好地控制四旋翼飞行器完成航拍任务。
[Abstract]:The FPGA voice recognition command is used as the aerial remote control command of four rotors. The ability of fast processing of information in FPGA is combined with the simple, accurate and flexible characteristics of voice control. The control system is divided into two parts. The four-rotor aircraft uses single-chip microcomputer and adopts fuzzy neural network pid to control the rotating speed of the four-rotor propeller to control the flight height and direction of the fuselage. The voice remote command uses FPGA and the optimized hidden Markov model is used to complete the command control of the fuselage flight attitude. The simulation results show that the voice-controlled four-rotor control system has strong real-time performance and can well control the four-rotor aircraft to complete the aerial photography task.
