Challenges:<br />

• Position-dependent control design<br />

– Put more a priori physical knowledge and structure<br />

about n<strong>at</strong>ure of plant vari<strong>at</strong>ions into LPV problem<br />

– Avoid conserv<strong>at</strong>ism (e.g. due to allowing infinitely fast<br />

vari<strong>at</strong>ions)<br />

• Changing resonance dynamics as a function of position …<br />

• … which is a function of time.<br />

• Speed of vari<strong>at</strong>ions depends on actual velocity, which is<br />

bounded!<br />
