[White Paper] Compensating For External Forces in Motion Control Applications
When an external force is applied to a system, standard PID parameters may not be sufficient to compensate for it. To better understand how to address this problem, four applications with external forces will be analyzed and an effective solution will be provided for each application. These applications include servo motors moving a vertical load, a spring load, a lever arm, and a compressible substance.

An HMI or Human Machine Interface is needed in many motion control applications. These devices are used to allow a user to instruct a machine on what to do without the need of a full PC. Many times HMIs are touch enabled allowing them to be placed on the production floor and used by technicians right by the machine. There are many sources for HMIs and many can cost thousands of dollars. With the arrival of the Raspberry Pi Foundation and its Raspberry Pi models, a small but powerful option arrived. Adding to this, the official Raspberry Pi 7” display, and the Galil application program interface, this powerful trio form the foundation for an inexpensive but fully capable HMI that can be customized for any motion control application.
