管内走行装置
Document Type and Number:
Japanese Patent JP3623028
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a running device in tube which is capable of securing a stable running control state under any status by estimating the running state amount regarding an estimating object kind based on an estimated reference output value and designating the amount as input information. SOLUTION: The detected output values detected by a detection means are divided into the groups of the values with high reliability, the values with low reliability, the values to be basically used for an estimation and the values to be defined as estimation objects, respectively. In each group, the former is defined as an estimation reference kind and the latter is defined as an estimation object kind. A running device 1 in tube is provided with a first estimation means 21 and an estimation side input determination means 23 and the running state amount of the estimation object kind (hereinafter referred to as first estimation value) is estimated from the output data on the side of the estimation reference kind. As the input information for the controller 20 regarding this estimation object kind, this first estimation value is inputted by an estimation side input determination means 22. Therefore, a sure control can be performed to perform the stabilizing control of the running device 1 in tube based on the output value with comparatively high reliability.
