Abstract
Abstract In this paper, the methyl isocyanate (MIC) hydrolysis reaction in a CSTR is used as an example to demonstrate the performance of a Lyapunov-based model predictive control (LMPC) system integrated with the activation of a safety system. Initially, in the presence of small disturbances, it is demonstrated that the closed-loop system state under LMPC is able to stay close to the operating steady-state and within the stability region. However, in the presence of a significant disturbance in the feed, the control system cannot maintain the closed-loop state inside the stability region, and thus, it has to be integrated with the reactor safety system to avoid thermal runaway.
