1747-NP1***1747-NP1***1747-NP1***机电控制是研究如何设计控制器并合理选择或设计放大元件、执行元件、检测与转换元件、导向与支承元件和传动机构等，并由此组成机电控制系统使机电设备达到所要求的性能的一门科学，在机电一体化技术中占有非常重要的地位。机电控制系统是机电一体化产品及系统中承担着控制对象输出，并按照指令规定的规律变化的功能单元，是机电一体化产品及系统的重要组成部分。机电控制系统是一种自动控制系统。机电控制系统一般由指令元件，比较、综合与放大元件，转换与功率放大元件、执行元件、工作机构、检测与转换元件等6部分组成。机电控制系统的工作原理是：有指令元件发出指令，通过比较、综合与放大元件将此信号与输出反馈信号比较，再将差值进行处理和放大、控制及转换，将此处理后的信号加到功率放大元件并施加到执行元件的输入信号，使得执行元件按指令的要求运动；而执行元件往往和机电装备的工作机构相连接，从而使机电装备的被控量（如位移、速度、力、转矩等）符合所要求的规律。ELECTROCRAFT9101-1131USPP91011131DYNAPARMT100S-00FNFPMT100S00TEXASINSTRUMENTSPLC500-5031NSPP5005031TEXASINSTRUMENTSPLC55CR9602001052USPP55CR9602001052ALLENBRADLEY1771-E2CNSPP1771E2CTEXASINSTRUMENTSPLC305-5DACNSPP3055DACTEXASINSTRUMENTSPLC990/305USPP990305MITSUBISHIMR-J2S-500BUSPPMRJ2S500BINDRAMATDKC04.3-100-7-​FWUSPPDKC0431007FWTEXASINSTRUMENTSPLC500-4005USPP5004005TEXASINSTRUMENTSPLC505-4216ANSPP5054216ACHINODB1230-000USPPDB1230000ENDRESS&HAUSERFMR240-S3K1ALJ​AA4AUSPPFMR240S3K1ALJA​A4BARBERCOLMANA-60010-708USPPA60010708ASEABROWNBOVERI3HAB2214-1/1USPP3HAB221411PanasonicACServoMotorMHMD042G1UNIBFreeShipMODICON140-DDI-364-00NSFP140DDI36400TexasInstruments8SlotPLCRack405U-20TU-15TU-25NASEABROWNBOVERIACS601-0009-4-​000B1500801USPPACS60100094000​B3MITSUBISHIBY171E584G51USPPBY171E584G51TEXASINSTRUMENTSPLC7MT-1100USPP7MT1100PANASONICSERVOMOTORMFA040LD2NSKNEWFASTSHIPPINGASEABROWNBOVERIACS601-0025-4-​000B1200801USPPACS60100254000​B1MITSUBISHIA3A-CPU-P21USPPA3ACPUP21PERCEPTRON911-0007TEXASINSTRUMENTSPLC575-4532NSFP5754532TEXASINSTRUMENTSPLC7MT-700NSPP7MT700ASEABROWNBOVERI1911RA00140000​0STDUSPP1911RA00140000​0SALLENBRADLEY1785-KA5NSFP1785KA5ASEABROWNBOVERIYYT-102DUSPPYYT102DOMRONF3S-A321-LUSPPF3SA321LASEABROWNBOVERIPSD110-1MM4USPPPSD1101MM4ASEABROWNBOVERIACS800-U1-0006​-5-L502-L503-N​660USPPACS800U100065L​52ASEABROWNBOVERI3BSE004940R1NSFP3BSE004940R1ASEABROWNBOVERIDCS602-0050-41​-15000C0USPPDCS60200504115​00PanasonicACServoDriverMSDA083A1ANewinBoxFreeShipPanasonicACServoMotorM***02A1EFreeShipALLENBRADLEY1775-AD1USPP1775AD1SiemensSimaticTI330PLCCPUModuleTEXASINSTRUMENTSPLC305-17ADCUSPP30517ADCPanasonicServoMSDA041D1A&MotorM***A041C1C400WLNCASEABROWNBOVERI57288001NSFP57288001GENERALELECTRICDS3800HXPA1D1DUSPPDS3800HXPA1D1DASEABROWNBOVERI6205BZ10100KUSPP6205BZ10100KASEABROWNBOVERISDTR16DBUSPPSDTR16DBGEFANUC44C331887-G01USPP44C331887G01ASEABROWNBOVERIDSDX-110NSPPDSDX110TexasInstrument500-588412ModuleI/Obase5005884A+GOSSWH715214-HNSPPWH715214HASEABROWNBOVERINDCU-22USPPNDCU22RELIANCEELECTRIC0-51901-ANSPP051901ATEXASINSTRUMENTSPLC5TI-3100USPP5TI3100NEWSIEMENSTEXASINSTRUMENTSTIINPUTMODULE500-5008CONTROLOTRON994DN5GS-3NSPP994DN5GS3YAMADAPUMPAD25-TTUSPPAD25TTTEXASINSTRUMENTSPLC505-6850BNSFP5056850BPERCEPTRON515-0108DIGITALSPOTLIGHTUSEDPerceptron96KDSPFrameGrabber495-0191RevNASEABROWNBOVERI57771682USPP57771682ASEABROWNBOVERIR58113972USPPR58113972TEXASINSTRUMENTSPLC500-5035USPP5005035Panasonic200WACServoDriveMSD021A1XUFreeShipASEABROWNBOVERIDSQC314BUSPPDSQC314B)
