Embodiment Construction
[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0047] like figure 1 As shown, the present invention mainly includes a pole position input module, a data acquisition module, a data processing and control module, a variable pitch propeller electric power device and an LCD liquid crystal display module. The present invention takes the data processing and control module as the center, first combines the pole position input module to complete the open-loop control of the variable pitch propeller electric power device; secondly combines the pole position input module and the data acquisition module to complete the control of the variable pitch propeller electric drive The single closed-loop control of the device; furthermore, the parameter identification of the linear model and the nonlinear model of the variable pitch propeller electric power device is completed by combining the pole position input mo...
