CH 4023 - Process Modelling and Simulation

Tutorial Matlab Simulink

1. For a mass-spring system where F is the external force applied on the mass

(m), K is the spring constant, a is the acceleration of the mass, u is the speed

of the mass, x is the distance that is covered and B is the friction factor the

motion equation is as follows. What is going to be the behavior of the mass

due to a sudden force change? Find the behavior of x and u with the time.

B=16, K=13.6,m=100, F= Step function of 0 to 1

How will the stability of the system will change with the friction factor?

2. The pendulum shown has the following nonlinear Deferential Equation.

Make a Simulink diagram suitable to solve this equation

3. Solve the following nonlinear Deferential Equation Take: m=1, c=0.1 k=1

4. Simulation of the impulse and step response of a second-order continuous-time transfer

Function

The following cases will be investigated:

(a) Underdamped: 0 < < 1

(b) Critically damped: =1

(c) Overdamped >1
