Technical field
The utility model relates to the servo vector closed loop control system of a kind of servo vector closed loop control system, particularly a kind of central air conditioner main machine compressor.
Background technique
Included by central air conditioner main machine compressor assembly, equipment has the primary clusterings such as main frame compressor, drying equipment, filter plant, transfer line.And be wherein maximum the consumption for the energy sources person with main frame compressor.In the energy conservation of compressed air system, first must require that the high efficiency of main frame compressor operates, therefore, the drive motor of central air conditioner main machine compressor preferably uses variable-frequency motor, namely adopt the AC speed-regulating mode of " special variable frequency induction motor+frequency variator ", mechanical automation degree and working efficiency are greatly improved.
But above-mentioned variable-frequency motor works in opened loop control usually, therefore it is to the control precision relative mistake of rotating speed, torque force, causes the performance of energy-conservation aspect unsatisfactory.
Model utility content
The purpose of this utility model is the servo vector closed loop control system providing a kind of central air conditioner main machine compressor in order to solve above-mentioned the deficiencies in the prior art.This system can realize energy-efficient object.
To achieve these goals, the servo vector closed loop control system of a kind of central air conditioner main machine compressor designed by the utility model, this system comprises:
For driving the mixed magnetogenerator of main frame compressor,
Mix rotary speed parameter value and the torque force parameter value of magnetogenerator for Real-Time Monitoring, and carry out the rotating coder unit that feeds back to servo driver unit,
For the feedback parameter values of rotating coder unit and setting command value are compared, and according to comparing the servo driver unit of the mixed magnetogenerator of difference control;
Wherein, both above-mentioned servo driver unit and rotating coder unit are connected with mixed magnetogenerator signal respectively, and rotating coder unit and servo driver unit each other signal be connected, mixed magnetogenerator and main frame compressor link.
The servo vector closed loop control system of a kind of central air conditioner main machine compressor in above-mentioned, it mixes rotary speed parameter value and the torque force parameter value of magnetogenerator by rotating coder Real-Time Monitoring, and feed back to servo driver unit, servo driver unit compares according to the feedback parameter values of rotating coder unit and setting command value thus realizes mixing the closed loop control of magnetogenerator, controls accurately the rotating speed of above-mentioned mixed magnetogenerator, torque force; Meanwhile, high pulling torque power and bearing capacity strong feature is exported when above-mentioned mixed magnetogenerator has possessed the slow-speed of revolution.Consider 2 above points, when native system controls the main frame compressor of central air-conditioner, it can realize energy-conservation object.
As further technological improvement, the servo vector closed loop control system of above-mentioned a kind of central air conditioner main machine compressor, it further comprises the machine internal pressure parameter value for Real-Time Monitoring main frame compressor, and the pressure sensing cell that feeds back is carried out to servo driver unit, pressure sensing cell and servo driver unit each other signal are connected, and servo driver unit compares according to the feedback parameter values of rotating coder unit and pressure sensing cell and setting command value thus controls to mix magnetogenerator.
Pressure sensing cell in above-mentioned is by the machine internal pressure parameter value of Real-Time Monitoring main frame compressor, and feed back to servo driver unit, thus make servo driver unit turn increase a reduced parameter value when realizing closed loop control, thus the control making servo driver unit can realize mixed magnetogenerator further more accurately.
The servo vector closed loop control system of a kind of central air conditioner main machine compressor that the utility model obtains, it is a servo vector closed loop control system on the whole, control relatively accurate, combine upper employing in its system again and mix the machine power output source of magnetogenerator as central air conditioner main machine compressor, possess relatively large bearing strength, can long-time stable work in high power work environment.Therefore, it has possessed energy-efficient control advantage.
