The study carried out in this paper unveils a survey on issues related to modelling
problems control strategies of a Continuous Stirred Tank Reactor (CSTR), a
highly nonlinear plant containing numbers of stable and unstable operating points
is considered. The issues discussed are categorised into regulation, feedback
linearization, flatness, observation and estimation as well as challenges related to
equilibrium points concerning CSTR. In this study, the limited capability of a
conventional PID controller is discussed based on preliminary description and a
dynamic modelling of the nonlinear plant. Moreover, the limitations of the
conventional PID is illustrated through a simulation using nonlinear model of
CSTR carried out under input constraint and the presence of bounded
disturbances. The result shows that a fixed PID will not guarantee consistent
performance throughout operating set points. The feedback linearization
formalism is presented to prove that only regulation in the neighbourhood of
operating point is possible. Non-minimum phase property exhibited by a CSTR
is investigated as well. Flatness control is demonstrated as one of the possible
linearization control technique achieving the objective of the trajectory tracking.
