PID is a widely used linear controller in industry field. However, PID is not sufficient enough to meet the increasing requirements because of the functional restrictions, like bode’s phase gain relation and waterbed effect. Nonlinear controllers are then interested by researchers. Reset control, as one of the nonlinear controllers, has more...

The demand for faster production times and higher precisions in the industrial automation is ever-increasing. Resonance modes caused by flexural elements in these machines are limiting the maximum bandwidth. Because of this, high-precision motion systems in industrial machines are limited in the maximum operating speed and precision. To improve...

In precision engineering, thermal stability is of great importance in order to keep up with the ever-increasing demand for faster and more precise positioning actuators. Most notably, actuator magnetizing coils dissipate heat to surrounding machine components as a result of Joule heating. With changing temperatures, system components expand and...

Settels Savenije van Amelsvoort is interested in investigating the use of piezoelectric shunt damping for a measurement and calibrations setup. The goal is to damp the remaining vibrations from previous vibration isolation stages to sub-nanometre amplitude. There was interest in piezoelectric shunt damping as a damping mechanism. Although...

Damping vibrations of flexible structures is a subject of importance in several industries, as the aerospace and high-tech industry. Especially when the ratio of damping over weight needs to be high. In literature optimization of this ratio is achieved in several manners, through optimization of individual damping methods, ie. active and passive...

As systems become more lightweight, to satisfy inertia and size requirements, vibration becomes a prominent factor in their dynamics. This vibration is undesirable and various suppression methods exist such as passive, semi-active, and active. In this thesis, active control methods are explored for this purpose. The present technology utilizes...

Buitenhuis, R.N. (author)
The ever-increasing industry desire for improved performance makes linear controller design run into its fundamental limitations. A nonlinear controller, such as Reset Control (RC), is needed to overcome these. RC is promising since, unlike other nonlinear methods, it easily integrates into the PID design framework preferred by industry. Thus...

Kieft, Bas (author)
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...

Delta robots can be improved by changing the conventional joints with compliant joints (CJs). This will enable a new type of machine without joint clearance, zero friction, no wear and no need for lubrication, which makes the delta robot suitable for clean environments and dynamic applications with low maintenance. Most research in the field of...

Floor vibrations are a common problem in high tech engineering where good tracking, precision and bandwidth have utmost importance. They are mainly present at low frequencies, and they need to be suppressed. PID control is the go-to controller in the industry because of its ease of design, simple implementation and good performance. However, PID...

Tall buildings lose a big part of their expensive space to elevator shafts. A ropeless elevator reduces the amount of shafts, because multiple cabins are able to move in the same shaft. Currently an elevator using a row of linear motors along the shaft is in the end phase of development. Tests on a full scale prototype 5 have proven the concept....

PID is the most popular controller in the industry. PID controllers are linear, and thus have fundamental limitations, such that certain performance criteria cannot be achieved. To overcome these limitations, nonlinear reset control can be used. Reset control can achieve less overshoot and a faster response time than linear controllers. However,...
