This paper describes design, construction and control of a 3-RRR planar parallel mechanism. The focus is on experimental control methods using inverse kinematic problem in order to gain more accuracy ...

There are two road forms of control architecture: open-loop and closed-loop. In open-loop systems, there is no ‘feedback’ mechanism; they operate on a ‘demand met’ basis. A typical example of open ...

Feedforward or open-loop control generates a command for the plant that is expected to produce the correct output. However, there is no measurement of the output from the plant, and hence no ...
