Ithustasion Od The System Of Interest Is Shown In Fig 1 A Thin Rod Havieg A Length D And Feglelele Mass In Pinned 10 1 (30.17 KiB) Viewed 47 times

ithustasion od the system of interest is shown in Fig. 1. A thin rod, havieg a length d and feglelele mass in pinned 10 a cart having a mass m. The red woports a ball of mass m. at its other end. The dimemions of the ball are assured to be small compared to the leneth of the ead 3 The cart follt withen triction aleng a flat surface. The comrel whtem is eesresented by the hoeicontal foece F, which is applied to the cart. (This force will generally vary with time.) A popolar approakh for the control signal f is 79 wse PiD conarel (+P−1−02). FiD stands for proportional integral-derivative. This means that f a made to be proportional to the onientation angle 4 by a chosen "gain" factor as well as factoes for both. Mashemutically, the ho control wheme can be express as F(t)=kp​θ(t)+k1​∫et​θ(t′)dr2+kB​θ(t) where kp1​​kp​ and kp​ are the gain factors for the proportional integral and derivative control components, respectively. Please note that these gain facters defer from one ansther in their respective dimesiont. f gure 1. Shematic of an imerted pendolum antached to a cart.
