| 摘要 |
<p>The invention relates to a system for controlling temperature, especially of a plastic extruder. Said system has a controller which is subdivided into an I-controller (1) which produces an integral-action component (y1) from a system deviation (xd), and a PD controller (2) which produces a proportional and a differential component (ypd) from a controlled variable (x). By superimposing said components in a summing element (3) a manipulated variable is produced. The novel controlling system is characterized by a good response to setpoint changes and simultaneously by a good interference behavior. The invention is used for adaptive controllers.</p> |
