Technical field
The invention belongs to electronic technology field, relate to a kind of monolithic processor controlled non-standard AC servo motor.
Background technology
Servomotor belongs to control motor, and it is divided into DC servo motor and AC servo motor two kinds.Due to AC servo motor, to have volume little, lightweight, large torque exports, the advantages such as low inertia and good control performance, be widely used in as executive component in automatic control system and automatic checkout system, the control signal of telecommunication be converted to the mechanical rotation of rotating shaft.Because the positioning precision of servomotor is quite high, it is the position control system of critical piece that modern position control system adopts more and more with AC servo motor.Here design also just by closed, the disconnection of control relay, and reaches the object controlling pulsewidth size, by the displacement of the slip magnetic patch of the non-standard AC servo motor of closed-loop control, utilizes changes of magnetic field to reach the object controlling motor speed.
AC servo motor is three phase alternating current motor; Driver control U/V/W three-phase electricity forms electromagnetic field; Rotor rotates under the effect in this magnetic field, simultaneously motor by proximity transducer by speed feedback signal to driver; Driver compares according to value of feedback and desired value, the angle of adjustment rotor turns.Servomotor, also known as operating motor, in automatic control system, as executive component, converts angular displacement on motor reel to the received signal of telecommunication or angular speed exports.
The Bit andits control of AC servo motor directly determines the performance of control, and in prior art, AC servo motor utilizes artificial experience Non-follow control, and governing speed is slow, and error rate is high.
Summary of the invention

Adopt monolithic processor controlled non-standard AC servo motor of the present invention, non-standard AC servo motor is controlled, effectively utilize single-chip microcomputer internal resource and understand the operation characteristic of corresponding motor kinetic control system in detail, in the corollary apparatus practical application of producing buncher, reduce the cost of system, improve the performance of system.
Accompanying drawing explanation
Fig. 1 illustrates the schematic diagram of a kind of embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Monolithic processor controlled non-standard AC servo motor, is characterized in that, comprise single-chip microcomputer, the photoelectrical coupler be connected and speed probe, the relay be connected with photoelectrical coupler, also comprises the display device that is connected with single-chip microcomputer and input equipment with single-chip microcomputer.
As shown in Figure 1, compared with the motor speed fed back by the tachometer value needed for key-press input motor and with speed probe, adopt pid algorithm, after single-chip microcomputer process, change into corresponding pulse signal, again through the aperture of photoelectrical coupler regulating relay, by the pulse duration of regulating relay, reach the modulation of pulsewidth, thus the positive negative displacement of magnetic patch on control servomotor, make the tachometer value that motor reaches given, single-chip microcomputer acceptance is simultaneously fixed on the feedback pulse signal that the speed probe in servomotor rotating shaft produces along with electric machine rotation, and the actual speed of motor is shown in real time at LED.The P0.0 of STC89C52RC, P0.1, P0.2 port, respectively as the input port of each button, by the Interruption control impuls transmission frequency of STC89C52 timer T0, and then controls the rotating speed of motor.Motor often rotates 1 circle, and single-chip microcomputer just interrupts 1 time.By detecting the time interval of twice interruption, namely by the counting of timer, just motor speed can be calculated.
Due to single-chip microcomputer belong to TTL circuit (logical one and 0 level be respectively 2.4 V and 0.4 V, the digital output modul signal level that its I/O mouth exports cannot direct-driving motor, so control raising speed signal output part at P2.6 mouth need add drive circuit; In like manner this drive circuit is also applied to the reduction of speed output of P2.7 mouth.System adopts optocoupler coupler and transistor to drive, and imports control motor into by photoelectrical coupler output channel, so have very strong restraint speckle interference performance, plays buffer action, can prevent strong electromagnetic; Transistor mainly plays power amplification effect.
Adopt monolithic processor controlled non-standard AC servo motor of the present invention, non-standard AC servo motor is controlled, effectively utilize single-chip microcomputer internal resource and understand the operation characteristic of corresponding motor kinetic control system in detail, in the corollary apparatus practical application of producing buncher, reduce the cost of system, improve the performance of system.
Previously described is each preferred embodiment of the present invention, preferred implementation in each preferred embodiment is if not obviously contradictory or premised on a certain preferred implementation, each preferred implementation can stack combinations use arbitrarily, design parameter in described embodiment and embodiment is only the invention proof procedure in order to clear statement inventor, and be not used to limit scope of patent protection of the present invention, scope of patent protection of the present invention is still as the criterion with its claims, the equivalent structure change that every utilization specification of the present invention and accompanying drawing content are done, in like manner all should be included in protection scope of the present invention.
