PROCESS CONTROL APPLET SERIES VI
Observe the effects of system pole/zero location on the step response
Objectives of This Applet
This applet is designed to illustrate the followings :
- - Step responses depending on pole/zero location
- - Pole location change at the same damping coefficient
- - Pole location change at the same time constant
- - Stability based on the location of poles
- - The effects of multiple poles/zeros
This applet consists of 3 parts. The horizontal thin panels on top and bottom are the control panel and status panel, respectively. The status panel is changing depending on the situation to give the explanation to users. In the Middle, there are two panels. The left panel shows the step response. The right panel shows the location of the poles and zeros.
Control Panel
(Upto 6 real or complex pairs of poles+zeors can be added.)
Add poles/zeros
: CLICK the location of poles/zero to add
Move points
: CLICK one of the poles or zero and DRAG to move the location
Delete poles/zeros
: CLICK the location of poles/zero to delete
Free move
: Move the poles and zeros to any location on the complex plane shown
Circular move
: Move the poles with constant distance from the origin (Constant time constant)
Linear move
: Move the poles with constant angle from the axis (Constant damping coeff.)
Middle Panel
This panel shows the uinit step responses. The gain is normalized and the x axis is fixed and y axis will be rescaled automatically except "superimpose" option is selected. If "superimpose" option in the status panel is selected, y scale will be frozen.
Up to 6 pairs of poles/zeros can be shown. Red circle and blue square indicate pole and zero, respectively. If a pole or zero is moved on top of other, the circle or square will be shown as a multiple circle or square. With the "Keep Multiple" option, multiple pole/zero can be moved together.
Status Panel
Superimpose
: By clicking the checkbox, plots can be superimposed.
Keep Multiple
: By clicking the checkbox, multiple poles/zeros move together.
Status shows location and multiplicity of the selected ponts.
Pole/zero Effects on Step Response (Java Applet will help you interactively.)
Will be given by the instructor
