E (PID) controlling the spindle speed. This approach was selected for
E (PID) controlling the spindle speed. This method was selected for numerous factors, such as control, as shown in Figure 3, using the thermocouple temperature as the input and conprevious excellent efficiency and ease of implementation on an existing FSW machine as trolling the spindle speed. This technique was selected for a number of factors, including previshown in [14]. A detailed comparison of unique temperature control procedures can also be ous excellent performance and ease of implementation on an current FSW machine as shown supplied in that reference. The controller gains are tuned via the auto-tuner, operating a in [14]. bead-on-plate weld at thedifferentfeedrate and set-point temperature.

Auto-Tuner The auto-tuner applied was an Diversity Library Description adaptive relay test, depending on a first-order plus dead-time The auto-tuner made use of was an adaptive relay to based on first-order plus dead-time The auto-tuner applied was an adaptive relay istest, basedadjust the rpm, plus dead-time model [18]. The basic concept of this auto-tuner test, slowlyon a a first-order in steps, to discover model [18]. The general concept of this auto-tuner isis to gradually adjust the rpm, in actions, to discover model [18]. The common concept of this auto-tunerconstant and in the temperature for which an rpm that keeps the temperature reasonably to gradually adjust the rpm, in measures, to seek out an rpm that keeps the temperature somewhat constant and atat the temperature for which the temperature for which an rpm that keeps the begins a series of steps constant of that rpm and watches how the you’re tuning. Then it temperature relativelyof +/- 10 and also you are tuning. Then it it begins series of of steps of +/-10 of that rpm and watches how the starts a a series actions of +/- ten of that rpm and watches how the you happen to be tuning. Then temperature rises and falls. This allows automatic method identification, and calculation temperature rises and falls. This permits automatic system identification, and calculation temperature rises and falls. Thisafter 5 “cycles” of +/- 10 . A typical and calculation.
