Determination of the thermal system parameters which simulates an exothermic chemical reactor with state space method and feedback control

In this project, a thermal system that physically simulating the exothermic chemical reactor had established and the parameters of a controller had determined by applying step forcing functions, which are the basic methods of the process control. The state space model of the system was created with the obtained values and the used mathematical equations, after then transfer function of the system between internal temperature of tank and jacket cooling water flow rate, has been found. In addition, after the findings transfer function of the system, stability conditions were determined with digital simulation and frequency response analysis. To control the system, a variety of controller parameters had tested on the digital simulation. By using these parameters, step and sinusoidal pulse inputs are examined on the system and the most suitable controller parameters were found for the system. Feedback control loop of the thermal system was created in Simulink environment and distorting factors applied to this cycle (Q heating and Ftnk ) after a certain time the stability has been brought back with regulation control system. Finally, a certain temperature value is assigned the thermal system, to reach this reference value is provided by the servo control system.
