Embodiment Construction
[0051] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0052] A robust detection method for intermittent sensor faults in the braking system of EMUs, the basic principle of which is as follows: figure 2 As shown, the process is as follows figure 1 As shown, it specifically includes the following steps:
[0053] Step 1: Establish the state space model of the brake system of the EMU, as shown in formula (1):
[0054]
[0055] in, is the system state, for the control input, is the measurement output; is the process noise, is the measurement noise; is the process parameter, is the measurement parameter; is the process parameter uncertainty, is the measurement parameter uncertainty; It is a multiplicative intermittent sensor fault, and its form is shown in formula (2):
[0056]
[0057] Among them, Γ(·) is the unit step function, F i is the mode of the i-th intermittent faul...
