(5) debugging step and parameter set
System relates to PID arithmetic, will be by following former when Set scale gain P value, the I value time of integration, D value derivative time Then arranging: the rotating speed proportional gain the biggest response of P value is the fastest, but system stability is deteriorated, excessive gain may result in rotating speed concussion; The least response of integration time constant I value is the fastest, and speed overshoot is the biggest, and stability is the poorest.This parameter is directly proportional to system inertia, used When measuring bigger, this parameter should arrange bigger numerical.
In main shaft accelerator effectively, numerical value relatively proportional gain 2 is big, is used for improving in parameter group medium speed proportional gain 1 Response speed;Proportional gain 2 adjusts for steady-state process PI, and in order to increase the stability of system, this parameter values is less.Accelerate During two groups of PI parameters can be automatically switched by stagnant ring or switching mode continuously.
(6) produced problem and solution in debugging
(1) there is vibrations and noise when running in motor
This phenomenon reason: excessive gain scale P value there is a possibility that rotating speed shakes, thus steady speed precision declines, and even makes system Unstable;Otherwise, accelerator is slow, and system response time reduces.Carrier frequency mainly affect operating audio-frequency noise and Heat effect: carrier frequency value is less, although improve converter can band ultimate load, but produce noise will can increase equally Greatly.
Solution: adjust suitable PID gain (F8.1.21 and F8.1.25);Increase carrier frequency.
(2) positioning precision is the highest, and positioning time is long
This phenomenon reason: too small position loop gain, result in system response time and slows down, under operating mode case of frequent changes Positioning precision declines.
Solution: increase the gain (Fb.2.21) of position ring PID.
(7) interpretation
After experiment Flood gate uses this frequency conversion targeting scheme process, converter reaches to exchange the performance that main axle servo drives, one Platform power of motor is to carry out trail run on the calabash of 18.5KW, and experimental result is as follows:
From the foregoing, it will be observed that used by actual production, apply the present invention to Flood gate and patrol and examine control, it is achieved that clamped one time, Save outer button and auxiliary reclay, and working (machining) efficiency also improves nearly 20%, can be effectively increased production efficiency, reduce Production cost, fully plays the superiority of economical Flood gate;Through prolonged application, this programme is stable, response is rapid, Positioning precision is high, is compared with prior art more suitably applied to lifting field.
