DEVELOPMENT OF CONTROLLER AND OBSERVER FOR CONTINUOUS STIRRED TANK REACTOR VIA STATE SPACE APPROACH

iii
ABSTRACT
This paper describes the designing, simulation and analysis of controller and observer for a continuous stirred tank reactor via state space approach. Many industries uses the conventional control system approach, as opposed to the modern control approach commonly used in aerospace industries. Conventional controls possess several drawbacks, for example PID controllers are not adaptive and not robust. Thus, qualities such as robustness, optimality and adaptivity could have been overlooked. This project is looking at modern control approach for plant control which is expected to be better in terms of the system’s controllability and stability. The entire project involves understanding the process control and state space, grasping the concept of system identification as well as mastering the function of MATLAB and Simulink for controller and observer design and simulation. Extensive utilization of MATLAB and Simulink were involved in several experiments and simulations. Results from the project indicate the practicality of modern control in plant process control system. This project successfully achieved the theoretical implementation of modern control engineering in plant process control systems, paving way for a possible design of a new controller and observer strategy that are robust, optimal and adaptive via modern control approach.
