Now, with the social and economic development, packaging machines more and more models, automatic vertical packaging machine general machinery for the above food, chemical, pharmaceutical, light industry, in order to process a complete multi-channel, digital packaging machines also gradually appeared in front of us, performance automatic vertical packaging machine automatic control system are: stability, speed and accuracy. Let's look.
1. Due to the stability of automatic vertical packaging machine automatic control system there is inertia, when the various parameters of the system of allocation is not the time, will cause oscillation system and lose the ability to work. Stability refers to the ability of the oscillation tendency and dynamic process to restore equilibrium. When disturbances or setpoint changes, the output will deviate from the original stable value, relying on feedback, through the mediation of automatic vertical packaging machine automatic control system inside the system continuously convergence over time, and finally back to the original stable value or follow a given value to stabilize. If for some reason, the system appears divergence in an unstable state, the system can not work. Stability requirements is a prerequisite system works.


2. Accuracy Accuracy is also called static accuracy means automatic vertical packaging machine automatic control system after the end of the adjustment process to the output of the deviation between the value indicating the accuracy of the system, but also an important measure of system performance in index. Some systems require high precision accuracy, such as position control. Depending on the specific circumstances of the controlled object, different systems for stable, accurate and fast requirements also vary. For example, the servo system for fast demanding, and speed control system is strict stability requirements. With - system performance steady, accurate, fast between each other constraints, fast performance good system, it is possible to easily oscillate; good stability of the system, it is possible to slow the adjustment process, the accuracy may deteriorate. Work should be based on the target system, specific analysis, to seize the main contradiction and taking into account other.
3. Because of inertia or fast energy power constraints, changes in automatic vertical packaging machine automatic control system of various magnitudes can not be mutated by a steady transition to the new steady state, it will take some time, That needs to undergo - a transition process. Fast that the system output when the deviation between the reference value generator with fast recovery system eliminates the deviation of the steady-state level.
