Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] figure 1 and figure 2 Partial flow charts of an embodiment of the method for suppressing the fluctuation of the rotational speed of the single-rotor compressor based on the present invention are respectively shown. Specifically, the speed fluctuation suppression method of this embodiment includes two processes: one is the process of controlling the compressor according to the real-time angular velocity, the flow chart is as follows figure 1 Shown; one is the process of controlling the compressor according to the torque, the flow chart is as follows figure 2 shown. The following is based on figure 1 and figure 2 , while combining image 3 A control block diagram is shown, respectively describing the concrete realization of these two ...
