Nonlinear controller design with prediction horizon time reduction applied to unstable CSTR system

Ensuring nominal asymptotic stability of the Nonlinear Model Predictive Control controller is not trivial. Stabilizing ingredients such as terminal penalty term and region are crucial in establishing stability. Current work presents alternate approaches namely arbitrary based approach linear quadratic regulator approach, which provide larger degrees freedom for enlarging against conservative from literature. Efficacy proposed demonstrated using benchmark two state continuous stirrer tank reactor system around an unstable operating point. Terminal regions obtained approximately 45 412 times by area measure when compared to largest As a result, there significant reduction prediction control horizon time.
