The RoPID Design Tool is a graphical user interface - GUI that allows you to design SISO feedback control systems. Using the RoPID Design Tool, you can design all PD, PI or PID controllers that stabilizing the plant.

Plant - serve for input of the transfer function of the plant for which we will design a controller.

Type of controller - with this item we specify the type of designed controller. For PID controller we must specify the fixed parameter too.

• PD
• PI
• PID

Range for parameters - has two possibilities

• Auto - this is the default value of the range (-10;10) with step 0.05.
• Manual - if we will specify other range we have two possibilities:
• The same range for both axis
• The different range for axis

Figure Menu - serve for some operation with:

• File - is menu item for basic operation with matlab figure (file).
• Data - in this menu item we can do this
• Import Plant
• Update data from workspace - update plant fields if are used workspace variables
• Get controller data from axes
• Create root locus
• Export controller data - export controller to workspace. Before export we must use Get data from figure to get controller data.
• Export region to figure
• Tools - here are basic axes function like zoom and edit plot

Context Menus - are available using right mouse button.

Evaluate - this is the button for simplify the controller.

Clear All - this button serve for erase all input fields.
