Description

Middle wire digital servo fuzzy self-adaptive control module

Technical field:

The utility model relates to a kind of electric machining adaptive digital fuzzy self-adaptive control module, particularly a kind of middle wire digital servo fuzzy self-adaptive control module.

Background technology:

Walk the silk cutting machine tool technology at present and used practicability substantially, in cost and the market prospects of considering research and development, the market middle-grade lathe of general development is main, make lathe to suitable machining accuracy, good processing stability, improve intelligent degree direction high and that keep low use cost and develop, promptly dominate the market with the good ratio of performance to price.

For in walk the general dual mode that adopts the silk cutting machine tool, the one, control the high-frequency electrical pulses origin system in real time according to the variation of machining state, the 2nd, according to the variation Self Adaptive Control servo feed system of machining state.

And in servo feed system in order to reach from motion tracking optimum Cutting state, generally need constantly detect and adjust to the line cutting discharge process.

Summary of the invention:

In order to reach the optimum Cutting state from motion tracking, the utility model provides a kind of wire digital servo fuzzy self-adaptive control module that is used for multi-state real-time sampling digital servo feed system.

The technical scheme that its technical problem that solves the utility model adopts is: wire digital servo fuzzy self-adaptive control module in a kind of, form by single-chip microcomputer 89C52, encoded control and store control logic circuit, E and Δ E memory circuit, decoding circuit, CPLD2RAM memory circuit:

Described encoded control and store control logic circuit receive conversion single-chip microcomputer 89C52 signal and are passed to E and Δ E memory circuit.

Described E and Δ E memory circuit receive encoded control and store control logic circuit and outside CPLD1 signal simultaneously, and the signal of handling is delivered to decoding circuit.

Described CPLD2RAM memory circuit is received in the address that forms in the decoding circuit, and form corresponding address with the result of reasoning and obtain the data of configured in advance in CPLD2RAM, form the adjustment amount Δ T of digital integrator and the adjustment amount Δ P of electric pulse pulsewidth, and adjustment amount come the digital integrator value of setting is revised T ± Δ T, with the adjustment P ± Δ P of pulse, form Fuzzy PD Control output.

By the utility model, receive and analyze the data that other circuit are sent here, thereby form adjustment amount, the line cutting discharge process is detected and adjusts, to reach from motion tracking optimum Cutting state.

Description of drawings:

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing is a structured flowchart of the present utility model.

Among the figure: 1, electrical quantity configuration single-chip microcomputer; 2, encoded control and store control logic circuit; 3, E and Δ E memory circuit; 4, decoding circuit; 5, CPLD2RAM memory circuit.

The specific embodiment:

Wire digital servo fuzzy self-adaptive control module in a kind of as shown in drawings, by electrical quantity configuration single-chip microcomputer 1, (wherein encoded control mainly is the sequential and the synchronous situation of control decoding for encoded control and store control logic circuit 2, storage control mainly is the sequential of reading and writing and seeing interfered circuit in the control store), the E and the Δ E memory circuit 3 that are used for stored parameter, be used to form the decoding circuit 4 of address, CPLD2RAM memory circuit 5 is formed, it mainly is that second dervative Δ e with the rate of change e of index U that cuts quality and U is as input, data line progressive die behind first CPLD1 coding is stuck with paste reasoning, concrete:

Described encoded control and store control logic circuit 2 receive and transform electrical quantity configuration single-chip microcomputer 1 signal, and are passed to E and Δ E memory circuit 3.

Described E and Δ E memory circuit 3 receive encoded control and store control logic circuit 2 and outside CPLD1 signal simultaneously, and the signal of handling is delivered to decoding circuit 4.

Described CPLD2RAM memory circuit 5 is received in the address that forms in the decoding circuit 4, and form corresponding address with the result of reasoning and obtain the data of configured in advance in CPLD2RAM, form the adjustment amount Δ T of digital integrator and the adjustment amount Δ P of electric pulse pulsewidth, and adjustment amount come the digital integrator value of setting is revised T ± Δ T, adjustment P ± Δ P with pulse, to reach the purpose of dynamic adjustment, and then dynamically control feed speed and electrical quantity, that the method for this fuzzy control adopts is MAX---the MIN method, this part forms Fuzzy PD Control.

It below only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
