Introduction:
The design of a motion system, see _figure 1, is considered.
The motion system consists of a flexible frame (5) upon which a motor (1) is
mounted that drives a cart (4) by means of a belt (2) and a spindle (3).
Part 1: Controller design:
The task specification is as follows: stroke hm = 0:1 [m]; motion time tm = 0:2
[s]; 3rd order path; maximum allowable setpoint error emax;set= 100 [micrometer].
