Description
Technical field
The utility model relates to a kind of efficient water system of Fractional Order PID control.
Background technology
Integer rank PID controller is because control algolithm is simple, parameter is easy to adjust, the advantages such as strong robustness are widely used in the Industry Control, yet in recent years, increasing research concern and controlled device or controller are the systems of fractional order, this is because the differential equation and integral equation that many control systems or real physical object are more suitable for arbitrary order represent, integer rank PID controller is because the simplicity of its control algolithm, therefore be only applicable to the minimum phase system of the single output of single input, and the different performance requirement of the control system that can not satisfy simultaneously, at definite large dead time, during the controlled system such as uncertain, need a plurality of PID controllers series connection just can reach desirable control effect.
The responding ability of Fractional Order PID Controller and antijamming capability are better than traditional integer rank controller, robust performance and adjusting function are better than traditional integer rank PID controller, this is so that Fractional Order PID Controller need not just effectively detecting parameter in the water supply network under the situation of a plurality of series connection, is controlled water system efficiently and stably.
The utility model content
The technical problem that the utility model solves provides a kind of take Fractional Order PID Controller as core.The order of Fractional Order PID is value continuously, further widened the range of choice of integer rank PID controller parameters, this is so that the Fractional Order PID Controller flexible structure, can be according to water system different performance characteristics and requirement, select suitable differential order and integration order, obtain the efficient water system of the Fractional Order PID control of best control effect.
For solving above-mentioned technical problem, the technical solution adopted in the utility model:
A kind of efficient water system of Fractional Order PID control, its special character is: comprise Fractional Order PID Controller, microcomputerized controller, water pump driver, water pump assembly, storage tank, sensor group, three tunnel of Fractional Order PID Controller connects respectively A/D converter, microcomputerized controller, D/A converter, the sensor group one tunnel that is arranged on storage tank is connected with Fractional Order PID Controller, another road is connected with A/D converter, and a road of D/A converter connects water pump driver, water pump assembly, storage tank successively.
Above-mentioned sensor group is made of pressure sensor, level sensor and flow transmitter.
Compared with prior art, the beneficial effects of the utility model:
Water system control procedure of the present utility model is take Fractional Order PID Controller as core, the order of Fractional Order PID is value continuously, further widened the range of choice of integer rank PID controller parameters, this is so that the Fractional Order PID Controller flexible structure, can be according to water system different performance characteristics and requirement, select suitable differential order and integration order, obtain best control effect; Water system of the present utility model adopts the mark Fractional Order PID Controller, so that the order of differentiator sum-product intergrator can not be integer, and it has Duoed two adjustable parameters than integer rank PID controller, can obtain than the better dynamic property of integer rank PID controller.
Description of drawings
Fig. 1 is the schematic diagram of utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises Fractional Order PID Controller 5, microcomputerized controller 6, water pump driver 8, water pump assembly 9, storage tank 10, sensor group, three tunnel of Fractional Order PID Controller 5 connects respectively A/D converter 4, microcomputerized controller 6, D/A converter 7, the sensor group one tunnel that is arranged on storage tank 10 is connected with Fractional Order PID Controller 5, another road is connected with A/D converter 4, and a road of D/A converter 7 connects water pump driver 8, water pump assembly 9, storage tank 10 successively.
Above-mentioned sensor group is made of pressure sensor 11, level sensor 12 and flow transmitter 13.
Fractional Order PID Controller 5 of the present utility model also is equipped with A/D converter 4, D/A converter 7, the signal that A/D converter 4 is sent sensor here carry out conversion and process after give Fractional Order PID Controller 5 and with its feedback quantity as Fractional Order PID Controller 5, the output quantity of controller transforms through D/A converter 7 and delivers to water pump driver 8 with the signal of voltage, water pump drives, and 8 parameters according to Fractional Order PID Controller 5 outputs decide the output of water pump assembly 9 in the storage tank 10.
Workflow: pressure sensor 11, level sensor 12 and flow transmitter 13 are used for respectively detecting hydraulic pressure 1, cistern water level 2 and discharge 3, and the parameter that detects sent in A/D converter 4, A/D converter 4 is given Fractional Order PID Controller 5 after data are processed and transformed, Fractional Order PID Controller 5 links to each other with microcomputerized controller 6 again, signal sent water pump driver 8 to after Fractional Order PID Controller 5 will transform through D/A converter 7, water pump driver 8 is according to the output of receiving 9 pairs of storage tanks 10 of signal deciding water pump assembly, therefore water pump driver 8 links to each other with water pump assembly 9, water pump assembly 9 links to each other with water tank 10 again, storage tank 10 is by pressure sensor 11, level sensor 12 and flow transmitter 13 take back Fractional Order PID Controller 5, with hydraulic pressure 1, water level 2,3 three parameter feedbacks of discharge return Fractional Order PID Controller 5.
