Ground cylindrical steel fluid storage tanks are widely used in different industries. Regarding the significance of these structures, it is important to establish their proper performance in earthquakes by evaluating their seismic performance. The present study examines the seismic behavior of an unanchored fluid storage system via ABAQUS after validation using an experimental model. Next, the ...

The liquid level control in Coupled Tank System is a basic problem in process industries. Many times the liquids will be processed by chemical or mixing treatment in the tanks, but always the level of fluid in the tanks must be controlled and the flow between tanks must be regulated in presence of non-linearity, disturbance and time varying system parameters. The control of liquid level in tank...

An LPG filling station incident in Korea has been studied. The direct cause of the incident was concluded to be faulty joining of the couplings of the hoses during the butane unloading process from a tank lorry into an underground storage tank. The faulty connection of a hose to the tank lorry resulted in a massive leak of gas followed by catastrophic explosions. The leaking source was verified...

This paper presents the design and modeling of State Feedback with integral controller to implement in a Non-linear Spherical Tank SISO process. By using state feedback, it controls the liquid level in the tank as desired .The aim of this paper is to compare the control performance between State feedback with integral controller with conventional ZN, Luyben Tyreus PI/PID, Controllers. The mathe...
