This Paper presents the Sliding Mode Control of a Distillation Colum System which are influenced by external disturbances or perturbations that are act along the input. The issue of robustness property to be studied only for Matched Perturbation or for Matched uncertainty. The switching surface design for Sliding Mode control to be interpreted as a static feedback selection problem .The switching hyper plane design to be carried out along with pole placement technique and Quadratic Minimization technique for regulatory problems or disturbance rejection problem .The results are obtained for the distillation column where the Eigen values are to be placed arbitrarily and optimally and the robustness property to be measured using the condition number or by obtaining norm of the state variables about where the Eigen values are placed in closed Loop

“…In the literature, a number of controlling procedures are proposed and implemented to operate the process loops in a safer working region. In real time cases, the widely preferred controllers are PI/PID, since these controller structures are simple to understand and easy to implement [5][6][7][8][9][10][11][12] .…”

Abstract-The main motivation of this manuscript is to develop a PID tuning procedure to improve the performance of the benchmark distillation column models using the heuristic firefly algorithm. A decentralised PID tuning approach is developed to design an independent PID controller for the top and bottom product loop. Minimization of a multi-objective function is chosen to guide the search process of the controller tuning procedure. The performance of the proposed approach is confirmed by evaluating the time domain parameters and the error values. From the experimental results, the main observation is that, proposed approach offers satisfactory result on the proposed approach and helps to achieve a reduced values of the time domain and error values. The proposed approach proves its efficiency in a benchmark Two Input Two Output (TITO) system. In future, this approach can be adopted to design controller for the multi-loop and non-linear systems existing in the process control literature. The proposed approach can also be compared against other heuristic approaches existing in the literature.

“…Lee et al [1] considered two loop controller and set point weight s to reduce peak overshoot. Shamsuzzoha & Lee [2] and Vijayan & Panda [3][4] designed set point filters to improve the loop performance and to decrease peak overshoot. Zhang [5] reported a simple set point filter to reduce the peak overshoot.…”

In industrial processes, unstable system produces undesirable peak overshoot. So, PID controller with compensator and set point filter is designed using direct synthesis method. The set point filter reduces the peak overshoot. PID controller with compensator improves the overall response of the system. In this method, the characteristics equation of the system with PID controller and a compensator is compared with a desired characteristics equation. A single tuning parameter is used to find controller parameters, compensator and set point filter.
