Problems solved by technology

[0004] When the controller works in the non-cascade mode, the given amount of the loop can be modified manually in the automatic state. When the control mode is in the cascade mode, the given amount of the control loop comes from the output of the remote or upper-level control loop, and cannot be modified manually. Loop given amount

Embodiment

[0041] An online guidance automatic control method is applied to the automatic control of the material volume in the cement mill cylinder. The stability of the amount of material in the cement mill barrel directly affects the stability of cement quality and output, and at the same time the amount of material in the cement mill barrel is one of the important factors affecting the cement output. The amount of material in the cement mill barrel is mainly controlled by adjusting the amount of feed into the mill, which is greatly affected by factors such as material, grinding body, and ventilation. The parameter constraint value changes with the cement model, material and other factors, so the existing automatic control method is difficult to meet the continuous and stable automatic operation control requirements. At present, the automatic control and manual control are relatively independent in the design of the control system. Since the automatic control system cannot meet the re...

Abstract

An online automatic control guide method. In an automatic mode, a control system modifies a control quantity u(k) according to an online guide control quantity u G (k), and the control system outputs the deviation Deltau GA (k) between the online guide control quantity u G (k) and an automatic output control quantity u A (k) and the increment Deltau A (k) of the automatic output control quantity u A (k); and in a serial mode, the control system modifies a given quantity r(k) according to an online guide given quantity r G (k), and the control system outputs the deviation Deltar GC (k) between the online guide given quantity r G (k) and a serial remote given quantity r C (k) and the increment Deltar C (k) of the serial remote given quantity r C (k). The method is applied in the field of automatic control and can modify the control output quantity and loop given quantity in different modes and realize online operation guide or preferential human interference at any time and avoid auto-manual switch operations required when modifying the control quantity in an automatic mode and avoid switch operations required when modifying the given quantity under serial control.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an online guidance automatic control method. Background technique [0002] General control devices or control loops include manual, automatic, and cascade modes. Manual mode refers to manually adjusting the control output; automatic mode refers to adjusting the control output according to the predetermined control law (algorithm) results; cascade mode refers to the control output of the control loop. The given quantity comes from the output quantity of the remote or superior control loop. [0003] When the control mode is automatic, the control output cannot be modified manually. If you need to modify the control output, you need to switch to the manual mode first, modify the control output, and then switch back to the automatic mode again. Since manual and automatic undisturbed switching is generally considered in controller design, when switching from manual mode to ...
