Introduction
As summarized in the previous sections, a mechatronics system can be partitioned into function blocks
illustrated in Fig. 20.1. In this chapter, we will focus on the actuator portion of the system. Specifically,
we will present a general discussion of the types of electromechanical actuators and their interaction
