T-Flex: A fully flexure-based large range of motion precision hexapod

Autor: Bram Seinhorst, Dannis Michel Brouwer, Wouter Hakvoort, Marijn Nijenhuis, Mark Naves

Publikováno v: Precision engineering, 72, 912-928. Elsevier

Six degree of freedom manipulation provides full control over position and orientation, essential for many applications. However, six degree of freedom parallel kinematic manipulators (e.g. hexapods) either have a limited range of motion combined wit

Flexure-based 60 degrees stroke actuator suspension for a high torque iron core motor

Autor: Marijn Nijenhuis, Mark Naves, Wouter Hakvoort, Dannis Michel Brouwer

Publikováno v: Precision engineering, 63, 105-114. Elsevier

For the actuation of flexure-based precision systems direct drive actuators are used to allow for precise manipulation. For this purpose, often iron-less direct drive actuators are used which do not suffer from parasitic magnetic forces. In contrast,

Active vibration isolation by model reference adaptive control

Autor: G.J. Boerrigter, MA Michiel Beijen, Wouter Hakvoort

Publikováno v: IFAC-PapersOnLine. 53:9144-9149

This paper proposes model reference adaptive control (MRAC) to actively isolate payloads from floor vibrations and direct disturbance forces. Adaptive feedforward control is used to counteract measured disturbances, whereas an adaptive feedback contr

The tracking performance of manipulators can be improved considerably by adaptive feedforward control (AFFC). However, complex kinematics hinder the application to parallel kinematic manipulators (PKMs). This paper proposes a compact and efficient fo

Filtered-error recursive least squares optimization for disturbance feedforward control in active vibration isolation

Autor: Wouter Hakvoort, MA Michiel Beijen

Publikováno v: IFAC-papersonline. 52(15):448-453

This paper addresses the filtered-error recursive least squares (FeRLS) algorithm for disturbance feedforward control in active vibration isolation systems. The controller structure consists of a generalized finite-impulse response (FIR) filter to in

Control Engineering Practice, 72, 90-103. Elsevier

This paper proposes a multi-input multi-output (MIMO) disturbance feedforward controller to improve the rejection of floor vibrations in active vibration isolation systems for high-precision machinery. To minimize loss of performance due to model unc

Publikováno v: Mechatronics, 36, 167-179. Elsevier

Vibration isolation of more than 40 dB is achieved for a Coriolis Mass-Flow Meter (CMFM) with integrated Active Vibration Isolation. A CMFM is an active device based on the Coriolis force principle for direct mass-flow measurements independent of flu

Publikováno v: Flow measurement and instrumentation, 40, 39-49. Elsevier

In this paper the quantitative influence of external vibrations on the measurement value of a Coriolis Mass-Flow Meter for low flows is investigated, with the eventual goal to reduce the influence of vibrations. Model results are compared with experi
