Optimal Design and Control of a Torque Motor for Machine Tools

This paper presents a systematic approach of optimal design and control of a surface-mount, permanent-magnet synchronous torque motor for the next-generation machine tools. A step-by-step procedure of optimization integrates multiple performance objectives and constraints to help the designer make the best decision on the final motor geometry from both design and control perspectives.

Neural Network Exploration Using Optimal Experiment Design

this paper I discuss another alternative for exploration: automatic, incremental generation of training trajectories using results from "optimal experiment design." The study of optimal experiment design (OED) [Fedorov, 1972] is concerned with the design of experiments that are expected to minimize variances of a parameter­ ized model.
