Embodiment Construction
[0044] Such as figure 2 As shown, the implementation steps of the magnetic flux feedback suspension control method of the EMS type low-speed suspension train in this embodiment are as follows:
[0045] 1) Pre-wind the magnetic flux induction coil on the outside of the wire package on the suspension electromagnet of the EMS low-speed suspension train, and detect the induced electromotive force of the magnetic flux induction coil when the EMS low-speed suspension train is running, and adjust the gain of the induced electromotive force in turn , integration, calibration and zero adjustment to obtain the magnetic flux density at the suspension gap; at the same time, collect the suspension acceleration and suspension gap of the EMS low-speed suspension train;
[0046] 2) Calculate the control rate of the suspension system according to the magnetic flux density at the suspension gap, the suspension acceleration, and the suspension gap;
[0047] 3) Generate the closed-loop control ...
