摘要： A system includes sensors configured to measure parameters related to a vessel including liquid level, gas flow rate, pressure in the vessel, temperature of the vessel, and feed-liquid flow rate. A signal processing unit receives sensor output signals and generates a first filtered output signal representative of liquid level, a second filtered output signal representative of gas flow rate, a third filtered output signal representative of feed-liquid flow rate, a fourth filtered output signal representative of vessel pressure, and a fifth filtered output signal representative of vessel temperature. A flow demand control unit receives the first filtered output signal and generates an output signal representative of feed-liquid flow demand. A shaping unit receives the second, fourth, and fifth filtered output signal and generates an output signal representative of shaped gas flow rate as a function of pressure, temperature, or combination thereof in the vessel. A liquid level control unit controls the liquid level within predetermined limits by controlling one or more components based on the output signals from the flow demand control unit, the shaping unit, and the third filtered output signal.

摘要： A Rankine cycle system is provided in which, in order to make a pressure (P) of a gas-phase working medium at the inlet of an expander (13) coincide with a target pressure (PO), a feedforward value (NFF) is calculated on the basis of the target pressure (PO) and a flow rate (Q) of the gas-phase working medium at the outlet of an evaporator (12), a feedback value (NFB) is calculated by multiplying a deviation (ΔP) of the pressure (P) of the gas-phase working medium at the inlet of the expander (13) from the target pressure (PO) by a feedback gain (kp) calculated on the basis of the flow rate (Q) of the gas-phase working medium, and the rotational speed of the expander (13) is controlled on the basis of the result of addition/subtraction of the feedforward value (NFF) and the feedback value (NFB). It is thereby possible to control the pressure of the gas-phase working medium at the inlet of the expander at the target pressure with high precision without changing the amount of liquid-phase working medium supplied to the evaporator.
