WebOct 1, 1984 · The floating-point model of the Kalman filter is simulated on matlab and then the design was translated into the fixed-point one using C language. The RTL version of the model was created in VHDL. WebDec 31, 2024 · The Kalman Filter uses the Kalman Gain to estimate the system state and error covariance matrix for the time of the input measurement. After the Kalman Gain is computed, it is used to weight the measurement appropriately in two computations. The first computation is the new system state estimate.
