Contents The Kalman filter’s most immediate applications have been for the control of complex dynamic systems, such as continuous manufacturing processes, aircraft, ships, spacecraft, and satellites. Figure 2. PDF. With linear • Attitude and heading reference systems • Autopilot • Electric battery state of charge (SoC) estimation • Brain–computer interfaces We provide a tutorial-like description of Kalman filter and extended Kalman filter. As it is generally known that a Kalman filter must be based on an accurate stochastic model and that a good stochastic model may increase the accuracy of a Kalman filter (Yang & Deng 2018; Lin et al. A common application is the guidance, navigation, and control of vehicles, especially aircrafts and exploration robots. Kalman filter is the most frequently used algorithm in navigation applications. , using an electrical diode to measure weight), (d) model the noise-the base Kalman filter The Kalman Filter algorithm is a powerful tool for estimating and predicting system states in the presence of uncertainty and is widely used as a fundamental component in applications such as target tracking, navigation, and control.
