The hardware control of the net 1, step motor (1)Pulse distributor when the direction of the level is low, the output of the pulse distributor as A minusB -The order of the C pulse cycle. When the direction of the level is high, the output of the pulse distributor as A minusC -The order of the B pulse cycle. 2), 3) add, deceleration control:。 Power amplifier will enlarge the output signal of current pulse distributor to the stator winding of the motor power supply, make the rotor of the motor output torque. 2. Microcomputer control stepping motor: at present, the digital control in servo system are mainly adopts the combination of hardware and software control method, which software control mode is commonly used microcomputer to complete. This is because the digital servo control device based on microcomputer complete compared with analog servo control device, has the following advantages: (1)Can obviously drop control device hardware capital. Faster, functional update of a new generation of microprocessor, the hardware cost will be very cheap. Small volume, light weight, less energy consumption is their strengths. (2)Can obviously improve the reliability of the control. Integrated circuits and large-scale integrated circuit uniform trouble-free (MTBF)Significantly longer than the discrete component of electronic circuits. (3)Digital circuit temperature drift is small, there is no parameters, the influence of the stability is good. (4)Hardware electrical Louis standardization. Adopted some shielding measures in the process of integrated circuit, power electronic circuits is too large to prevent electromagnetic interference problems caused by the transient current, voltage, and high reliability. (5)Using microprocessor digital control, the information two-way transmission can be greatly enhanced, easy and upper machine combined transport system, may at any time change the control parameters. (6)Able to plan suitable for the unification of the power electronic system hardware circuit, which software can modular programming, control algorithm of assembly structure is suitable for various application goal; In order to satisfy different use. Software module can easily add or change, reducing or thoroughly updated when the actual system changes. (7)Improved information storage, monitoring, diagnosis and classification control ability, make the servo system tend to be more intelligent. (8)Follow the microcomputer chip constantly improve the computing speed and storage capacity, excellent but algorithm of complex function control strategy is the foundation of complete.
