Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the invention clearer, specific implementation manners will be described below in conjunction with the accompanying drawings.

[0023] attached figure 1 It is a structural diagram of the electric loading system that the control method acts on. The system uses a PC host computer to simulate the loading command signal required by the electric loading system, and uses DSPF28335 to realize the control of fuzzy CMAC and fuzzy reasoning machine. In DSP, in addition to receiving command signals, it is also necessary to feed back the output torque signals, and use these signals to perform related operations of fuzzy CMAC and fuzzy reasoning machine. The loading instruction signal is finally transmitted to the driver of the controlled torque motor to control the torque motor to generate the corresponding load. The torque sensor can measure the output torque signal, which is amplified and output to the PC host co...

Abstract

The invention belongs to the technical field of motor control methods, and particularly relates to a novel electric loading system control method. For solving the problem that loading accuracy and stability of an existing intelligent electric loading system control method are difficult to ensure, the compound control method based on fuzzy CMAC and an indistinct logic computer is provided. The control method includes the steps that in fuzzy CMAC control, a loading instruction signal is mapped to all units in space, then membership degrees of an input signal to all fuzzy sets serve as weight information of corresponding weight values, and weighting summation is carried out on all the weight values to obtain preset output approximate values. Meanwhile, activated input fuzzy sets in the indistinct logic computer are mapped into all output fuzzy sets, and an improved high defuzzifier is used for calculation to reach increment needed by preset output; finally the two are added to obtain a final output signal. The electric loading system control method based on fuzzy CMAC and the indistinct logic computer can improve system control precision and ensures system stability.

Description

technical field [0001] The invention belongs to the technical field of motor control methods, and in particular relates to a novel control method for an electric loading system. Background technique [0002] The rudder surface of the aircraft will be subjected to aerodynamic loads during flight. In order to ensure that the steering gear can fly normally while bearing these loads, the bearing capacity of the aircraft steering gear needs to be fully tested on the ground. The electric loading system can generate loading torque through the torque motor to simulate various loads received by the steering gear when it is working, and test the performance of the steering gear in the laboratory environment, which can shorten the development cycle and improve the flight reliability. [0003] In the electric loading system, the excess torque caused by the movement of the steering gear will affect the loading accuracy of the system, and will also narrow the frequency band of the system ...
