To capture the velocity of the ball just before the collision, the output port of the Second-Order Integrator block and a Memory block are used. Notice the loop for calculating the velocity after a collision with the ground. For the bouncing ball model, this option therefore implies that when the ball hits the ground, its velocity can be set to a different value, i.e., to the velocity after the impact. This parameter allows us to reinitialize ( in the bouncing ball model) to a new value at the instant reaches its saturation limit. Navigate to the Attributes tab on the block dialog and note that the option 'Reinitialize dx/dt when x reaches saturation' is checked. Navigate to the Second-Order Integrator block dialog and notice that, as earlier, has a lower limit of zero. The second equation is internal to the Second-Order Integrator block in this case. ![]() You can use a single Second-Order Integrator block to model this system. Using a Second-Order Integrator Block to Model a Bouncing Ball Note, however, the chatter of the states between 21 seconds and 25 seconds and warning from Simulink about the strong chattering in the model around 20 seconds. Therefore, you can now simulate the system beyond 20 seconds. This algorithm introduces a sophisticated treatment of such chattering behavior. ![]() In the 'Zero-crossing options' section, set the 'Algorithm' to 'Adaptive'. Now navigate to the Configuration Parameters dialog box. Consequently, the simulation exceeds the default limit of 1000 for the 'Number of consecutive zero crossings' allowed. Observe that the simulation errors out as the ball hits the ground more and more frequently and loses energy. In the 'Zero-crossing options' section, confirm that 'Algorithm' is set to 'Nonadaptive' and that the simulation 'Stop time' is set to 25 seconds. To observe the Zeno behavior of the system, navigate to the Solver pane of the Configuration Parameters dialog box. The state port of the velocity integrator is used for the calculation of. The state port of the position integrator and the corresponding comparison result is used to detect when the ball hits the ground and to reset both integrators. This condition represents the constraint that the ball cannot go below the ground. Navigate to the position integrator block dialog and observe that it has a lower limit of zero. The Integrator on the left is the velocity integrator modeling the first equation and the Integrator on the right is the position integrator. You can use two Integrator blocks to model a bouncing ball. Using Two Integrator Blocks to Model a Bouncing Ball Models with Zeno behavior are inherently difficult to simulate on a computer, but are encountered in many common and important engineering applications. Hence the model experiences Zeno behavior. As the ball loses energy in the bouncing ball model, a large number of collisions with the ground start occurring in successively smaller intervals of time. Zeno behavior is informally characterized by an infinite number of events occurring in a finite time interval for certain hybrid systems. Ī bouncing ball is one of the simplest models that shows the Zeno phenomenon. The bouncing ball therefore displays a jump in a continuous state (velocity) at the transition condition. ![]()
