ABSTRACT
This chapter presents the design and implementation of a family of adaptive. The concept of exact model knowledge, output feedback (OFB) control was demonstrated for certain motors; however, there does not appear to be a method for designing adaptive, OFB controllers for any of the multiphase machines. The chapter shows that the mechanical subsystem can be generalized to apply to all the motor types considered thus far. The electrical dynamics are then given for the permanent magnet stepper, switched reluctance, and brushless dc motors in preparation for the controller design. A pseudo-velocity filter is proposed to generate a velocity related signal for use in the closed-loop controller. The implication of the inequality is that, based on the asymptotic tracking of each term on the right-hand side of the inequality, asymptotic velocity tracking is also achieved. Therefore, the proposed controller can be used as a velocity tracking controller by reformulating the desired velocity tracking objective as a position tracking objective.
