The dynamic error of CNC machine tools, which often exceeds the quasi-static error at high-
speed machining, becomes the main reason affecting the machining error of the sculptured …

The precision of machine tools is essentially determined by the feed drive control. To
improve the dynamic behavior of elastic feed drives, this paper presents a novel position …

This paper presents an optimal non-collocated control strategy for flexible ball-screw feed
drives. Within the non-collocated controller framework, all the feedback measurements are …

This paper presents a new method for designing accurate motion control laws for high-
speed feed drives with structural flexibility. The controller design utilizes only table (load) …

高档数控机床是支撑航空, 航天及能源工程等领域零件加工的关键装备. 当前我国已经可以设计
和制造各种结构型式的高档数控机床, 但是机床的性能与国外先进产品相比仍然存在一定差距 …

An adaptive sliding mode control method based on the fuzzy exponential convergence law
is proposed to solve the jitter problem caused by the sliding mode control of the servo-feed …

Most feed drives in machine tools are designed using ball screw drives. The bandwidth of
such drives with conventional PPI control principle is limited by the first natural frequency of …

This paper presents a new control structure for ball screw drives (BSDs), which achieves
position tracking through an outer loop, and active vibration damping for dynamic stiffness …

This article presents a hybrid model to predict the positions of the ball screw drive system of
machine tool and then modify the trajectory through constructing a pre-compensation …

Owing to the elasticity of transmission systems, actuated joints suffer from dynamic errors
that seriously affect the tracking accuracy. Mainly drawing on the full closed loop control …
