Requiring a rapid response for a large mass

Reference no: EM131127857

Electrohydraulic servoniechanisms are used in control systems requiring a rapid response for a large mass. An electrohydraulic servomechanism can provide an output of 100 kW or greater [17]. A photo of a servo valve and actuator is shown in Figure P9.8 (a). The output sensor yields a measurement of actuator position, which is compared with V_in. The error is amplified and controls the hydraulic valve position, thus controlling the hydraulic fluid flow to the actuator. The block diagram of a closed-loop electrohydraulic servomechanism using pressure feedback to obtain damping is shown in Figure P9.8 (b) [17, 18]. Typical values for
