“…This result is important because it indicates that the UT can be used to choose locations to obtain results similar to those obtained using the Monte Carlo method. It is worth noting that the UT has traditionally been used in problems related to parameter estimation, filtering, automation, and control [21][22][23][24][25]. In the last years, it has been used in a variety of new problems, including some in the telecommunications sector as an alternative to Monte Carlo methods [26][27][28].…”

In a drive test, it is common to measure the electric field strength (or other related quantity) at fixed intervals to calibrate propagation models or to optimize wireless network coverage. We propose to select the measurement locations based on the unscented transform. Using just a few points (tens rather than thousands), we show that the statistics of the measurement tends to the correct value, which can save time and reduce the cost of drive tests.

Slip controller is an essential part of the locomotive controller because it enables maximum force transfer and increases the service life of the locomotive parts. The modern slip controllers try to determine actual adhesion parameters and set the required tractive force to avoid slippage occurrence. Many types of the slip controller methods were developed, and one of developed principle try to determine adhesion parameters from phase shift between motor torque and corresponding speed measured on the motor or wheelset. The paper presents a novel evaluation procedure for the phase shift calculation that is based on the Kalman filter that enables directly compare force corresponding with the motor torque and the adhesion force. The method principle is described in the paper, and the method performance is evaluated on the mathematical model.

“…The high‐frequency torque components can cause problems in some applications. A good example is a locomotive where the adhesive force is estimated for slip control purposes [7]. For this method, the motor torque must be as smooth as possible.…”
