Control can be introduced in numerous different ways. The following are indicated by L.E. BAYLISS (1966 — retranslated from the spanish translation — original unavailable):
- auto-adaptive: Return of a system's function toward its most adequate value by automatic change of the parameters (1968, p. 118).
- integral: Control operated upon a deviation, that becomes matematically integrated in time (p.42)
- nonlineal: Intermittent control according to the existence of thresholds and saturation points in the process (p.42). (This is the on-off control).
- proportional: Control operated by a regulating device that produces at one moment a signal proportional to the deviation (p.38).
- variable: Control operated by a regulating device on the base of memory of former deviations (p.42).
Volitive controls could be added, being those that man establishes in artifical or natural systems that he wants to modify to his advantage.
