The authors demonstrate that if feedback control and component reliability design criteria are considered simultaneously, significant gains in reliability may result. The discussion begins with a tutorial introduction to probabilistic design for reliability. Simple examples are employed to illustrate the analytical tie between feedback control and component reliability. In the case of modal control, it is demonstrated that fast response and component reliability are competing criteria. The question of system (as opposed to component) reliability is discussed in a succeeding paper.

The One

In this chapter, three control methods recently developed for or applied to electric motors in general and to permanent magnet synchronous (PMS) motors, in particular, are presented. The methods include model predictive control (MPC), deadbeat control (DBC), and combined vector and direct torque control (CC). The fundamental principles of the methods are explained, the machine models appropriate to the methods are derived, and the control systems are explained. The PMS motor performances under the control systems are also investigated. It is elaborated that MPC is capable of controlling the motor under an optimal performance according to a defined objective function. DBC, on the other hand, provides a very fast response in a single operating cycle. Finally, combined control produces motor dynamics faster than one under VC, with a smoother performance than the one under DTC.
