One 、 Job content

These two days I started to write 《Fusion Estimation for FDI Sensor Attacks in Distributed Systems》 The simulation of .

29 I finished writing the simulation framework , The main thing is to write the model , The emphasis is on the setting of augmented matrix and the dimension of some related matrices , After adjustment, it can run through , It indicates that there is no problem with the dimension , But the estimation of parameters is not convergent , The problem this time is different from that last time .

30 Daily tune BUG.
Wrote a one-dimensional , Still not converging .
Consider that the dimension is too low , The measurement dimension is the same as the attack dimension , Raise status to 2 dimension , To no avail .
Another standard was written AKF, Under the setting of system fault , Use standards Kalman The filtered results and AKF The result of the method for state estimation is the same , That is to say AKF The method focuses on the estimation of fault parameters , Instead of eliminating at the same time .
Now I begin to suspect that there is something wrong with the system model I understand , Because the given model uses AKF Algorithm , At present, I can't explain it personally .

Two 、 Experience
