Frequency Scale Conversion From f To f Scale frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch. frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear. frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.

This demonstration models a flight control for the longitudinal motion of a Grumman Aerospace F-14 T

This demonstration models a flight control for the longitudinal motion of a Grumman Aerospace F-14 Tomcat. First order linear approximations of the aircraft and actuator behavior are connected to an analog flight control design that uses the pilot s stick pitch command as the set point for the aircraft s pitch attitude and uses aircraft pitch angle and pitch rate to determine commands. A simplified Dryden wind gust model is incorporated to perturb the system.

四軸同款傳感器方案設計ICM20602+AK8975+SPL06-001

四軸起飛時，發出觸發信號使導航模塊開始工作，同時讀取ICM20602的加速度計、陀螺儀數據，對數據卡爾曼濾波后姿態解算，對角度與角速度采取串級PID調節?？刂葡到y算法設計主要有ICM20602濾波算法，姿態解算算法、串級PID控制算法和定高部分控制算法。礙于篇幅所限，下面介紹最重要的串級PID控制算法和定高部分控制算法。地理坐標系中重力的水平分量為零，僅用三軸陀螺儀和三軸加速度計無法計算出航向角，由于巡線機器人保持穩定飛行只需要橫滾角（roll）和俯仰角（pitch），所以四元數轉換成歐拉角。定高控制算法采用的是增量式PID控制，定高控制的輸出最后與姿態控制的輸出疊加到四個電機的控制中。數據濾波使用的是低通濾波，采用近三次的平均值。為了防止姿態對激光測距的影響及減小高度控制對姿態控制的干擾使用歐拉角來校正高度值，即Hight=(float)Hight*(cos(roll)* cos(pitch))。將四元數轉換后的歐拉角與陀螺儀測出來的角速度進行串級PID控制，其中歐拉角作為外環，角速度作為內環。外環的PID以及內環的PD設定值為測試數據值。由于內環的角速度控制不需要無靜差,所以內環采用PD控制,為防止測量的誤差造成較大影響,外環積分需要限幅。
