Title: Numerical control method e.g. for position and speed of electric motor of railway vehicle
Inventor: KNAUF THOMAS DIPL ING
IPC: G05B19/19
Filed: 1996-05-23
Granted: 1997-07-24
Abstract: The invention concerns a digital method of regulating linear regulating processes which is suitable in particular for regulating the position and speed of loads moved by an electric motor, the rotational speed and position of the motor being regulated simultaneously. The regulation can also follow a continual variation in the reference variable, e.g. for continuous path control systems or when, on multi-axis machines, the movements according to the different axes are to be adapted to one another. As a function of the settling time available for the respective regulating process, the regulator calculates a rectilinear curve of the correcting variable (of the motor current) which leads to the target in a dead beat manner. The regulation is highly precise, rapid, stable and robust. In comparison with conventional controllers (of the PD and possibly the PID type) the advantages are the shorter settling times, lack of inherent instability, greater rigidity, easier adjustability and fewer motor energy losses. In addition, it is known in advance when the regulating target will be reached. The digital regulator can be constructed simply and economically with a microcomputer.
