This system is always in great Accepted 21 2 2022 demand in the chemical industry petrochemical refining water treatment Published 28 4 2022 power generation construction material production food processing automatic liquid dispensing and replenishment devices. The terminal sliding mode control TSMC schemes not only ensure that the system states arrive KEYWORDS at the equilibrium point in a finite time but also offer some attractive Terminal sliding mode control properties such as their fast response and higher precision than traditional New Quasi-sliding mode function sliding mode control. The new quasi-sliding mode function will eliminate high frequency oscillations phenomenon around a sliding surface also Chattering known as chattering of the sliding mode control. This phenomenon causes Two tanks interacting instability in the system the power driver circuits are susceptible to MATLAB Simulink. overheating resulting in damage. Simulation results in MATLAB Simulink show that the proposed method is suitable to control the liquid level s position of the two tanks interacting system with without the percent overshoot the steady state error is eliminated the settling time is s the rising time achieves s and the chattering phenomenon is eliminated.
