So now, lets find the transfer function of the pendulum … Again note that the names of the inputs, outputs, and states can be specified to make the model easier to understand. The actual concept of the inverted pendulum to be tested by the group can be compared to balancing an umbrella on the tip of one’s finger or to that of a Segway as can be seen in Figure 2. This example shows how to model an inverted pendulum. The controller needs to keep the pendulum upright while moving the cart to a new position or when the pendulum is nudged forward by an impulse disturbance dF applied at the upper end of the inverted pendulum. controller to maintain this position. Also, you will learn how to draw the cart in Matlab, for fun.

The unstable nature of the plant makes the control task more challenging. This thesis investigates the standup routine and stabilization at the inverted position of a pendulum-cart system. The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F. Determine the dynamic equations of motion for the system, and linearize about the pendulum's angle, theta = Pi (in other words, assume that pendulum does not move more than a few degrees away from the vertical, chosen to be at an angle of Pi). The purpose of the arm is to provide a balancing torque to a swinging pendulum, to keep the pendulum in an upright position. The problem “control of an inverted pendulum” was proposed to understand various control strategies and concepts. Session 18: State-Space and Phase-Plane (116-122). This system is unstable and highly nonlinear with one input - voltage of a DC motor which can change position of the cart and two outputs - cart position and angle of the pendulum rod.
