机电一体化答案（Mechatronic solutions） Mechatronics papers (a) two, fill in the blanks (every day 2 points, a total of 20 points) In the 1. cycle cycle 2. performance index system function use condition of economic benefits 3. PLC4. 20mm 5. 0.027. 6. position and velocity decreases with the increase of 8. 29. in 10. simple linear feedforward controller in motion control Three, choice (to match each 2 points, a total of 10 points) 1. B.2. A3. C.4.C 5, D four, to determine the problem (every day 2 points, a total of 10 points) 1, 2, 3, V * V * 4, 5, five (V, Q A to match each 10 points, a total of 30 points) 1. single power supply circuit, double power supply circuit, chopping current limiting drive circuit, 2. step error, step error directly affect the positioning accuracy of the executive parts. The maximum static torque is a stepping motor in a phase always energized in the stationary state, the maximum torque and can withstand the maximum torque, which can output, it reflects the braking ability of stepping motor and low load capacity in run time step. Start torque frequency characteristics, no-load stepper motor start suddenly from rest, without stepping into the steady speed, the maximum allowable frequency is called the highest starting frequency. The starting frequency is related to the load torque. When running the torque frequency characteristic, the highest frequency acceptable to the stepper motor in its continuous operation is called the highest operating frequency, which determines the maximum operating speed of the actuator with step angle. The maximum phase voltage and maximum phase current respectively refers to the maximum current of stepping motor each phase winding voltage and the maximum power allowed through applied. 3. should include system function, performance index, application condition, economic benefits. Six, the analysis calculation (every day 10 points, a total of 20 points) 1. 20KHz 3.6o 2. (1): (2) the ladder mnemonic instruction program: STR
