Control of liquid level in Interacting Two Tank Hybrid System (ITTHS) is highly challenging due to variation in the area of cross section. The modelling of such hybrid systems is different from the convention modelling techniques. Modelling and designing controllers for hybrid systems is an upcoming research area. This paper describes the modelling and control of such a highly non-linear system and also implementation of PID controller.  The modelling of such hybrid systems is different from the convention modelling techniques. PID controller has been designed for this process application. Piecewise linearization technique was applied for linearizing non-linear system output. For all the five regions, separate PID controller has been designed and simulated using MATLAB. The performance measures of the system are tabulated.

Abstract


Control of liquid level in Interacting Two Tank Hybrid System (ITTHS) is highly challenging due to variation in the area of cross section. The modelling of such hybrid systems is different from the convention modelling techniques. Modelling and designing controllers for hybrid systems is an upcoming research area. This paper describes the modelling and control of such a highly non-linear system and also implementation of PID controller.  The modelling of such hybrid systems is different from the convention modelling techniques. PID controller has been designed for this process application. Piecewise linearization technique was applied for linearizing non-linear system output. For all the five regions, separate PID controller has been designed and simulated using MATLAB. The performance measures of the system are tabulated.
