Crusher load automatic control adjustment parameters

LIMA Fish Feed Machine,Chicken Feed Machine

Automatic control system adjustment is stable, whether the error between the target value and the actual value reaches the process index requirements, when there is interference, the transition process time is short. These are the main indicators that measures the quality of the automatic control system to adjust the quality. The tuning of the adjustment parameters is to give the self-control system to achieve the best control effect. The adjustment parameters mainly have a control cycle, a P (scale factor), I (integral coefficient), and D (differential coefficient).

1. Control Period Tuning: After the object is determined, the pure lag time can be measured by the stopwatch, and the control cycle is tested. Mainly based on the size of the pure latching time. From the perspective of system stability, it is desirable that the shortestity of the pure latching time is, which is conducive to the fast elimination of the system of the system. However, for pure latch control objects, rapid control is caused to cause unstable system, and oscillate will occur when severe. By determining, the executing mechanism configured by the pulverizer is different, and its pure latching time is also different. The lag of the electromagnetic vibrating feeder and the aerodynamic film regulating valve is generally 3 seconds; the lag of the molten release is generally 5 seconds. The resurgence of the strap, the pttal lag is hidden. In order to control the versatility of self-control, the setting range of the controller control cycle is 2 to 7 seconds.

2. PID parameters are tailored: How to adjust to make the system get the best control effect, PID parameters are tailored to the key, in order to more The problem can be explained, and the graphical method can be used to analyze the control curve.
