Description
Summary:This paper presents the regulation of the continuous sliding mode controller applied to an unstable chemical reactor. The temperature of an unstable chemical reactor cannot be easily measured accurately due to its nonlinearities such as thermal runaway, saturation, delay, backlash etc. The nonlinearities which are present in an unstable chemical reactor are taken as unmodeled dynamics also the parametric uncertainties of the system are given as an external bounded disturbance by which robustness can be achieved by sliding mode controller. Further the asymptotical convergence of the system is achieved by making the state variables to reach the equilibrium point even from far away initial points by implementing terminal sliding mode and fast terminal sliding mode. The performance of the controller is shown in a comparative table when combinations of high frequency oscillating disturbance, low frequency oscillating disturbance and a constant disturbance are given to the system.
