Understanding Smart Actuators: Beyond Traditional Motion Control

A conventional actusator - whether ir hydraulic, pneumatic, or elecelecelecmechanical - converts energy into mechanical motion. It follows a command signate, but it does nots sense its environment. A smart actuator, by contrast, is a closed-loop system in miniatur.
