Abstract

The embodiment of the invention provides a variable structure control algorithm. The variable structure control algorithm adopts an incremental PID control mode, and the incremental PID control mode changes control structure parameters in real time through real-time changing system deviation and deviation change rate. The incremental PID control mode comprises a proportional gain part, an integralgain part and a calculus gain part. The calculation formula of the incremental PID control mode of the variable structure control algorithm is shown in the specification. The variable structure control algorithm has the advantage that the algorithm model can smooth the whole system control and adjustment process.

Description

technical field [0001] The present disclosure relates to the technical field of industrial control, in particular to a variable structure control algorithm. Background technique [0002] In industrial control, electro-hydraulic control is a typical time-delay control system, which requires high control performance such as control accuracy, adaptability and robustness of hydraulic control algorithm. The working principle of the hydraulic control system is to adjust the hydraulic oil flow through the electronic control system, and then change the current hydraulic pressure, so as to drive the relevant execution structure to respond, and collect the current position of the actuator, and judge whether the current adjustment control process has met the requirements. [0003] From the functional analysis, the hydraulic control system needs to adjust the hydraulic flow in real time to realize the real-time adjustment of the hydraulic pressure; from the performance analysis, the hyd...
