Abstract
The system includes a control system for deriving control variables from parameters which influence the productivity of the spinning machine (RS). Besides parameters which are measured by sensors, for the purposes of the control consideration is also given to those parameters which are not measurable or measurable only with difficulty. The last-mentioned parameters are included in the control system by means of a fuzzy logic, for which purpose the control system exhibits a fuzzy controller (FC).
Claims7
A system for regulating the operation of a spinning machine to optimize its production, comprising:
- sensors for measuring parameters relating to the operation of a spinning machine;
- a control system responsive to the measured parameters for generating control variables having an unambiguous mathematical relationship to respective measured parameters;
- means for entering other parameters which are not measurable with sensors;
- and
- a fuzzy logic controller which receives the control variables generated by said control system and other parameters which do not exhibit an unambiguous mathematical relationship to control variables, for a generating regulated variable for controlling the operation of the spinning machine.
