Question

Solve the following using simulink.1) The Pit and the Pendulum. Below is the equation for a pendulum. Make a Simulink model of this equation: -k sin(θ) dt2 Compare this model to the simplified model: 2 dt Let k-2. Use as initial conditions, Θ 0.1 and de/dt 0. Print out the model and the results of each equation. What is the difference in the period of the pendulum depending on the model? Repeat with initial conditions of Θ-1.0 and de/dt-0.1

Answer #1

Both the models are simultaneously given below

when theta = 0.1 and dtheta/dt = 0. Then the response is as follows green line is for the top model and the blue line is for the lower model

when theta = 1 and dtheta/dt = 0. Then the response is as follows green line is for the top model and the blue line is for the lower model

The first model has very large period as compared to the second model
