| Abstract: | This paper introduce detailed the feature and principal of smart power integreted circuit(SPIC). The design method of servo amplifier based on SPIC is described. Ac cording to the requirement of flight control system of some unmanned pilotless helicopter, a high accuracy servo amplifier in which L292 is addopted is developed successfully. It is valified by lab and flight test that the servo amplifier behaviers high reliability, good performance, and meet completely the requirement of flight control system of some unmanned pilotless helicopter. |
