- B-4-10. Consider the liquid-level control system shown in We assume that the velocity of the power piston (valve) K₁.x where K₁ is a positive constant. We also assume that the change in the inflow rate q, is negatively proportional to the change in the valve opening y, or Figure 4-52. The inlet valve is controlled by a hydraulic is proportional to pilot-valve displacement .x. or integral controller. Assume that the steady-state inflow rate is and steady-state outflow rate is also, the steady-state head is , steady-state pilot valve displacement is X = 0, and steady-state valve position is Y. We assume that the set point R corresponds to the steady-state head H. The set point is fixed. Assume also that the disturbance inflow rate 94, which is a small quantity, is applied to the water tank at = 0. This disturbance causes the head to change from to H+h. This change results in a change in the outflow rate by qo. Through the hydraulic controller, the change in head causes a change in the…arrow_forwardFind the differential equation and define the type of the control low. Draw the control structure.
