The LabControle is a simulation software for linear control systems. It is designed to be used as an auxiliary tool for teaching classical control system theory.
When the process phase for small frequencies starts in values less than 180 degrees (for example -270 degrees), the program interprets this as a positive angle (+90 degrees for this example). Thus, the gain and phase margins in the bode diagram are not properly displayed.
