摘要
Dynamic flow rate information is needed in a lot of applications; however it is normally not measurable. Calculation of the flow rate from fluid pressure dynamic equations usually results in poor estimates due to the very noisy pressure measurements and unavoidable modelling uncertainties. This paper proposes a sliding mode dynamic flow rate observer to estimate the meter-in and meter-out-flow rates of a hydraulic cylinder. Theoretical convergence can be guaranteed and simulation and experimental results show the effectiveness of the proposed flow rate observer.
