Embodiment Construction

[0023] Such as figure 1 As shown, a fuzzy PID compound controller is installed on the road surface cold recycling machine, and the spraying flow in the spraying system of the road surface cold recycling machine is controlled through the compound control of fuzzy control and PID control. The fuzzy PID compound controller passes the flow sensor Measure the current flow rate of water in the water pipe and the rate of change of the flow rate, and control the speed of the water pump according to the target flow rate set by the system to achieve precise control of the flow rate of the sprayed water.

[0024] In the controller, first set the deviation threshold Δ for switching between the PID controller and the fuzzy controller in the compound controller L q . The fuzzy PID composite controller obtains the parameters obtained from the sensors installed on the vehicle to measure the vehicle speed and the milling depth of the rotor, and calculates the target flow through the transfe...

Abstract

The invention discloses a cold reclaimer spraying control method based on fuzzy PID (Proportional-Integral-Derivative) composite control and relates to the technical field of cold reclaimer spraying control. The method comprises the following steps: installing a fuzzy PID composite controller on a road cold reclaimer, wherein the fuzzy PID composite controller is composed of a switchover judging module, a fuzzy controller module and a PID controller module; controlling the spraying water flow of a road cold reclaimer spraying system through the composite control of the fuzzy controller and the PID controller; adopting the fuzzy control under a large deviation; adopting the PID control under a small deviation; and switching over the two controllers through a software switch so as to realize good control on the spraying control system. The method has the advantages that the spraying control system can be operated on a selected objective flow well; rapid precise control of the system on the sprayed water quantity is realized; and the quality and the efficiency in road cold reclaiming construction are improved greatly.

Description

technical field [0001] The invention relates to the technical field of spraying control of cold recyclers, in particular to a spray control method for pavement cold recyclers based on fuzzy PID composite control. Background technique [0002] my country's highways are mainly asphalt roads, but due to the low design and construction standards of asphalt roads in my country for a long time, this has doubled the workload of road surface maintenance and renovation, and the demand for engineering materials has greatly increased. At the same time, a large amount of waste materials also have an increasing impact on the natural environment. Therefore, the recycling of asphalt pavement has been mentioned on the agenda. The in-situ cold recycling technology of asphalt pavement enables the reuse of old pavement materials, which can effectively solve a series of problems such as waste of resources and environmental pollution. It is an effective measure in line with the law of sustainab...
