Abstract

Hysteresis on the liquid level system(HOLLY)-based water tank liquid level systems show popular in testing multivariable control systems for multivariable processes with positive or negative zeros. When showing the relationship between the quantity of state and the variables of state in the substance obtained by test bed, it can be seen to draw a loop phenomenon which the quantity of state is not consistent at the time of increasing and decreasing after the variable of state was increased or decreased cyclically in a predetermined range. This phenomenon is called hysteresis. In some exothermic reactors, ignition and extinction temperatures are different. The ignition temperature is greater than the extinction temperature. It shows hysteresis for increasing and decreasing the reactor temperatures. Similarly, hysteresis occurs in ferromagnetic materials and ferroelectric materials, as well as in the deformation of some materials such as rubber bands and shape-memory alloys in response to a varying force. Test bed to inspect like as nonlinear dynamics are complicated construct and operate. To solve this, a liquid level system advanced a great deal such hysteresis process by using siphon occurrence. Siphon has become aware of hysteresis in our liquid level system named the hysteresis on the liquid level system(HOLLY). This HOLLY is compact size and even simply assemble parts for the process control. Apart from anything else this is not produce wastes. Here a supplementary dynamic aspect with siphon applying a hysteresis process is proposed.
