Automatic Door Controller February Solution Note Doors that must detect impediments and jams require frequent adjustment and are therefore expensive to maintain. Intelligent door controllers must respond to many different real-world conditions and inputs. They read badges, and alter their operation on a time schedule or in response to security alerts. How do we build an intelligent door controller that tracks long term changes in the environment, triggers reliably, and has a minimum of false positives? Read on find out! READ MORE Torque Feedforward: Getting The Most Out Of Your Motion Controller Means Feeding It More Information A Technical Deep-Dive Many motion applications require high accuracy both during, and at the end of, the move. Even if you are using perfectly optimized PID (proportional, integral, derivative) values to control position, the compensation loop is never perfect because it must manage the influence of a wide range of system forces. Can we improve performance by adding control elements outside of the PID loop? Take a deep-dive into PMD's lab to find out!
