PID, referred to together as a P-P/F PID. Both PIDs must be tuned and some method (such as a pressure threshold) used to transfer between the modes, so only one PID is operating at a time. For many applications, a pressure limit mode is the best solution (see Figure 3). In this case, both PIDs run simultaneously, and the minimum output is used. Much can be discussed about P- P/F control and future articles will cover this topic in more depth. Summary Machine designers need to know that one size doesn’t fit all in terms of hydraulic motion control. There are many control algorithms used in hydraulic applications, and the right one to use depends on the control needs of the application (see the table in Figure 4 for a summary). Some applications can benefit from combining two or three of the control algorithms discussed, depending on what part of the machine cycle is running. Discussing your application with the motion controller manufacturer early in the design process will help ensure that the controller has the algorithms you need. www.deltacomputersystems.com Figure 4.
