Demonstrates a controller for a chemical reactor transitioning from low to high conversion rate

The process considered here is a Continuous Stirred Tank Reactor (CSTR) during transition from low to high conversion rate (high to low residual concentration). Because the chemical reaction is exothermic (produces heat), the reactor temperature must be controlled to prevent a thermal runaway. The control task is complicated by the fact that the process dynamics are nonlinear and transition from stable to unstable and back to stable as the conversion rate increases. The reactor dynamics are modeled in Simulink. The controlled variables (states) are the residual concentration and the reactor temperature , and the manipulated variable (action) is the temperature of the coolant circulating in the reactor's cooling jacket.
