Template updating kalman filter
from one time-step to the next given some control input. Any system model must derive from the base and defining the corresponding jacobians.
The small sized outlet ports of the cylinders resist the flow of discharged oil; and as a result the piston motion is slowed down. Due to the time delay between issuing motor commands and receiving sensory feedback, usage of the Kalman filter supports the realistic model for making estimates of the current state of the motor system and issuing updated commands. In the prediction step, the Kalman filter produces estimates of the current state variables, along with their uncertainties.Once the outcome of the next measurement (necessarily corrupted with some amount of error, including random noise) is observed, these estimates are updated using a weighted average, with more weight being given to estimates with higher certainty. It can run in real time, using only the present input measurements and the previously calculated state and its uncertainty matrix; no additional past information is required.A common application is for guidance, navigation, and control of vehicles, particularly aircraft and spacecraft.Furthermore, the Kalman filter is a widely applied concept in time series analysis used in fields such as signal processing and econometrics.
