This paper adopts the fuzzy PID control method to resolve the hydraulic cylinder position servo control of direct-drive pump control system. The system model and fuzzy PID control algorithm was established by using AMEsim/Simulink joint simulation platform. The step response and Sine tracking performance of the system with PID and fuzzy PID control algorithms was investigated by simulation. At the same time, the performance of PID and fuzzy PID control was studied on the self-developed electro-hydraulic servo control experiment table. The results show that the adaptive fuzzy PID control can greatly improve the performance of the PID control, and has the characteristics of fast response, short rise time, small time delay and overshoot.10aAdaptive fuzzy PID control10aAMESim/simulink10aDirect-drive pump control system10aLabview10aPosition servo control1 aZheng, J.-M.1 aHe, M.-J.1 aLiu, E.-D.1 aYuan, Q.-L.1 aXiao, J.-M.1 aTang, A.-F.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84900429525&partnerID=40&md5=987ea43b8cb58e566d21061a4b7a355801788nas a2200205   4500008004100000245008100041210006900122260000900191300001400200490000700214520111100221653002201332653002201354653003001376653001601406100001601422700001101438700001601449856011701465       2013                        eng d00aA hybrid method to deformation force of high-speed cold roll-beating forming0 ahybrid method to deformation force of highspeed cold rollbeating  c2013  a146 - 1530 v113 aHigh-speed cold roll-beating forming technique is a new near-net plastic forming method that the intermittent high-speed roll-beating is used to achieve dynamic impact local loading, and that is fast, transient, high impact, large deformation of the complex forming process. For this forming process, the main stress method is employed to derive an analytic formula for the deformation force. Taking into account the main stress method can not reflect impact factors such as high-speed transient roll beating in process of this analytic solution, then the ABAQUS/Explicit is applied to simulate for highspeed cold roll- beating. The regression analysis is used to correct for the analytic formula based on simulation results, which makes the analytic formula more accurate reflection of deformation force of the different technological parameters of high-speed cold roll-beating. The forming experiments are carried out with self developed high-speed cold roll-beating experimental equipment and the experimental of deformation force is measured to verify the correctness of the corrected analytic formula.10aCold roll-beating10aDeformation force10aExperimental verification10aSlab method1 aYang, M.-S.1 aLi, Y.1 aYuan, Q.-L.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84879119848&partnerID=40&md5=beed77f3dd930748bf1900ffca1e5ad0
