The most widely applied feedback controller is PID. This controller gains its popularity because of the ease of design through loop shaping, since PID can be analyzed in the frequency domain. However, PID is limited by linearity. Reset control is a nonlinear addition to PID control. Through linearization techniques it can be designed by...

The PID controller is one of the most used controllers in the industry. However, fundamental limitations due to linearity restrict its performances when higher bandwidth, stability, and precision are required simultaneously in today’s high-tech industry. Reset control is a promising nonlinear control strategy which can overcome these limitations...

The application of actively controlled micrometer precision positioning stages in products that are accessible to start-ups, individual consumers or third world countries is currently limited by their price and size. To solve this problem, the use of low-cost and compact components in stages is investigated. Earlier research done in the MSD...

To push the performance of the next generation Ultimaker 3D printers further, a new positioning system is required to improve the printing speed, print accuracy and print repeatability. The expectation is that a linear motor positioning system will perform significantly better than a conventional belt driven system. For this reason, the aim of...

A new concept was developed to improve current airpot designs for vibration isolation solutions. The concept is based on an additional piston, or add-on, with certain characteristics, that is to be incorporated into an existing airpot-design. The effect of this add-on will passively improve the vibration isolation performance of the airpot. This...
