With the rapid development of aerospace, energy, and power technologies, the demand for
high-performance parts with complex curved surface is increasingly large, and the multi-axis …

This paper reviews the progress in machine tool control during the last three decades. Three
types of controls are discussed:(i) Servocontrol loops that control the individual axes of the …

This paper discusses experimental robot identification based on a statistical framework. It
presents a new approach toward the design of optimal robot excitation trajectories, and …

Abstract System inversion is at the basis of many feedforward and learning control
algorithms. The aim of this paper is to analyze several of these approaches in view of their …

Noncollocated sensors and actuators, and/or fast sample rates with plants having high
relative degree, can lead to nonminimum-phase (NMP) discrete-time zero dynamics that …

In this paper, a novel perfect tracking control method based on multirate feedforward control
is proposed. The advantages of the proposed method are that:(1) the proposed multirate …

To achieve the high precision required in future contouring machining applications, accurate
servo-controllers for the feed drives are needed. For this purpose conventional P controllers …

The dynamic response of a machine tool is a complex interaction of several factors that
includes the basic design of the machine as well as the capability and performance of the …

A limited-preview filtered B-spline (FBS) approach for minimizing errors in tracking a desired
trajectory is presented. In the full-preview FBS approach, the feedforward control input to a …

Single-track hard disk drive (HDD) seek performance is measured by settle time, t s. In this
paper, we show the effective use of feedforward dynamic inversion, coupled with reference …
