球桿系統課程設計
1. 直角桿兩端的小球桿做功
1.A:B=1:3 因為速度V=R*@ 角度用@表示
2.m*3r*sin(@-90) =2m*r*cos(@-90)
B球轉過的角度@=90+arctan(2/3)
3.mv*v/2+2m*(v/3) (v/3)/2=mg*3r+2mg*r 就用連乘拉 見諒
B的速版率大小v=根號權下90gr/11
2. 請問這個傳遞函數的作用和原理,它是一個二階濾波器嗎
你可以討論該傳遞函數對應的頻率響應，即s在虛軸上的取值，s=jΩ
所以H(jΩ）=1/(1-0.005Ω^2+j0.135Ω),將Ω回值帶入就可答以求出模值，而後就能看出是什麼通了
omega=0:1000;
H=1./(1-0.005*omega.^2+j*0.135*omega);
plot(omega,abs(H))
3. 求助一道關於剛體定軸轉動的題 (大學物理)
繞中心轉動。
碰撞後質點的動量全部轉移給球桿系統，系統質心以v/2勻速直線運動專。同時系統以角屬動量J=mvl繞質心轉動。
另一端怎麼可能不動呢？如果饒它運動，他一定受到另一端的拉力，可是這個力沒有和他平衡的！
張力T=m*w*w*(l/2),w為角速度。w=J/I。轉動慣量I=2*m*(l/2)(l/2).
代入可得：T=2mv*v/l,指向質心。
沖量=入射質點動量=mv
4. 球桿系統（ball and beam system）（400字翻譯）
Ball-beam system for automatic control, machinery and electronics, electrical engineering and so on the basis of professional courses designed to control the teaching experiment equipment, because the ball-beam system with the characteristics of open-loop instability, the need to design the controller to control the location of the ball, and its structure is simple and intuitive to understand. To meet the principle of automatic control, modern control engineering courses, such as the experimental requirements, but also can be used as motor learning, motor and drag, pattern recognition, such as laboratory equipment courses.
Ball-beam system is divided into the mechanical parts and control part of the two major components. Mechanical parts is a typical four-bar linkage, with a scale bar from the stainless steel rod and a linear displacement sensor that can pivot around its left rotation, the point of view through the control bar, you can control the ball in the location bar. Mechanical parts of DC servo motor-driven, by controlling the motor shaft angle, you can achieve the control point of view of the bar. Intelligent control of parts of IPM100 servo motion controller, IPM100 is based on the latest DSP controller technology, 36V, 3A all-digital intelligent servo drive unit can control the DC brushless, brush, or permanent magnet synchronous AC motor. The location of the ball through the linear displacement sensor acquisition, controller position error calculated in accordance with the volume control to control the motor shaft angle, the angle of the control bar so that the stability ball to the target location.
5. 剛體碰撞，剛體無彈性，碰撞後如何運動
碰撞後質點的動量全部轉移給球桿系統，系統質心以v/2勻速直線運動。同時系統如果是完全彈性碰撞，那麼運動質點施與剛體的沖量就等於它原來的沖量MV。非
