This simulator calculates the impulse response of a second order system, and plots that response in a phase plane.

• In the simulator, we assume that G(s) is a second order system.
• G(s) = G_dc/(s² + 2zw_n + w_n²)
• In the simulator, the following items can be set.
• z - The damping ratio for G(s)
• The magnitude of the impulse input to the system.
• In the simulator, the following items are fixed.
• w_n - The natural frequency = 1.0
• G_dc - the DC gain = 10.0
• To operate the simulator,
• Enter the parameters as listed above.
• Click the Start button.  A plot will be generated in real time.
• If you want to change anything, enter the new data, then click the Reset button which appears when the plot is complete.  That clears the plot and brings back the start button.
