Phase Plane Analysis
• Phase Plane Analysis can be used to find stable states in a system
• Phase Planes can be used to see the effects of changing system parameters

Example: CSTR with Heat Exchange
Example from Wiki page:ODE & Excel CSTR Model w/heat exchangehttp://controls.engin.umich.edu/wiki/index.php/CSTRHeatExchangeModel
• CSTR at steady state• Exothermic reaction• Heat exchange (cooling jacket)
CSTR with Heat Exchange
V=3000 L
Phase Plane Analysis Application
• Use PPlane to create phase planes
• Phase Planes can be used to determine stability and the number of stable states
• Phase plane analysis is useful for choosing operating parameters
