Optimal Kalman Filtering for a Class of State Delay Systems with Randomly Multiple Sensor Delays

الملخص EN

The optimal Kalman filtering problem is investigated for a class of discrete state delay stochastic systems with randomly multiple sensor delays.

The phenomenon of measurement delay occurs in a random way and the delay rate for each sensor is described by a Bernoulli distributed random variable with known conditional probability.

Based on the innovative analysis approach and recursive projection formula, a new linear optimal filter is designed such that, for the state delay and randomly multiple sensor delays with different delay rates, the filtering error is minimized in the sense of mean square and the filter gain is designed by solving the recursive matrix equation.

Finally, a simulation example is given to illustrate the feasibility and effectiveness of the proposed filtering scheme.
