OPTIMAL DESIGN AND ANALYSIS OF A CHEMICAL PROCESS CONTROL SYSTEM

The present work describes the design and analysis of a chemical process control system. The design is accomplished to attain the optimality of control operation. The total system is supposed to consist of the suitable controller operated in the closed loop manner with negative feedback path, affording the suitable output to the input. The optimality of the performance for the system is considered to be attained with gain of the (PD) controller [1], so chosen that the integral square error becomes a minimum. The overall system is found to be stable, controllable, and observable. The system is also analyzed in sampled data control domain (z domain). The stability in z domain is analyzed using Jury’s Stability test. MATLAB software is appropriately used in the entire analysis.
