Design Controller Using the Design Tool

3-17

This adds a pulse to the T output. The pulse begins at time t = 10, and lasts 20 time

units. Its height is 0.95 degrees.

Run the simulation. The output response plot displays the pulse (see Response Plot

Showing Open-Loop Pulse Disturbance). In this case, the T output's nominal value is

zero, so you only see the pulse. (If the T output had a nonzero nominal value, the pulse

would add to that.)

Response Plot Showing Open-Loop Pulse Disturbance

If you were to run a closed-loop simulation with this same T disturbance, the controller

would attempt to hold T at its setpoint, and the result would differ from that shown in

Response Plot Showing Open-Loop Pulse Disturbance.

Customize Response Plots

Each time you simulate a scenario, the design tool plots the corresponding plant input

and output responses. The graphic below shows such a response plot for a plant having

two outputs (the corresponding input response plot is not shown).
