Maple-SYREP Time Domain Analysis Example  

This example shows some of Maple-SYREP's time domain response functions.  A simple second-order mass-spring-dashpot system with a force input is created using a linear graph description, and used for the demonstration responses. 

•  The system responses to singularity function (impulse, step and ramp) inputs are then computed and displayed as closed-form functions of time. These functions are then plotted. (Note the difference between this approach and numerical packages such as MATLAB where approximate numerical integration is used to obtain responses.) 
• The response to a set of output initial conditions (y(0) = 2 m/s, y'(0) = -1 m/s^2) is then computed.
• The system response to a pulse at time t=1 sec, and lasting for 4 secs is plotted.  (The Maple Heaviside() procedure produces a unit step).
