In mathematical terms we'd say that a Kalman filter estimates the states of a linear system. There are two reasons you might want to know the states of a system, whether linear or nonlinear: First, you might need to estimate states in order to control the …
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.

WebIdeally, we can carefully pick a gain manually, but that is no easy task. This is where the dude Kalman comes in. This dude took the derivative of the gain with respect to the error, set it to zero, and give a gain such that error can be minimized.
