Energy optimization of a certain class of incremental motion DC drives

A joint approach to the design and control of energy-optimal incremental motion, load-invariant DC drives is presented. The drive is to rotate a given load through a definite angle in limited time, at minimum energy dissipation in the motor windings. It is required that the motor be of the minimum possible rating. An energy-optimal multimode control strategy for the drive is developed, and its microprocessor-based implementation is proposed. The motor and the so-called key parameters of the drive are determined by graphical solution of a nonlinear constrained optimization problem. A design example is included to illustrate the theoretical considerations.<
