AI Technical Summary

Technical Problem

When faced with nonlinear rheological characteristics, the timing of the driving energy injection in the existing concrete feeding control system coincides with the extreme point of internal friction of the material, resulting in feeding pulsation and mechanical fatigue of the pipeline network. Furthermore, the fluid dynamics model is difficult to solve in real time due to insufficient computing power of the on-site processor.

Method used

By acquiring real-time current sequences, calculating cumulative power consumption characteristics, constructing virtual time base reference sequences, adjusting sampling step sizes, loading high-frequency disturbance signals, avoiding high impedance regions, establishing the injection topology of driving energy, and achieving timing alignment and active feedforward compensation.

Benefits of technology

It eliminates the mismatch between drive commands and physical impedance, improves the response accuracy of the actuator under high viscosity conditions, avoids mechanical fatigue, and shortens the system steady-state error convergence time.

Abstract

The present application relates to the technical field of industrial control, and discloses a concrete feeding management and control method based on information-physical fusion, comprising: collecting current sequences in a sampling time window of a driving unit, generating power consumption cumulative characteristic quantities representing impedance changes through discrete integral operation; constructing a virtual clock reference vector of discrete time stamp dimension, and implementing local density mapping according to the characteristic quantities, adjusting the sampling step when the characteristic quantities exceed a preset threshold, so that the control pulse avoids the physical high resistance area; loading a high-frequency disturbance signal before issuing an instruction to overcome static friction resistance, and then determining the action time in combination with the processed reference vector, the present application effectively solves the phase step-out problem caused by the nonlinear rheology of concrete by reconstructing the time sequence topology of the information space, eliminates the mechanical response lag, and enhances the stability of the management and control system.
