Abstract: | |
This paper presents the investigation results and a controller implementation example of robust control concepts: non linear sliding mode control and linear model based µ-synthesis control. The challenge to transfer modern control concepts from research to industrial application is tackled by showing necessary steps performed for the controller implementation on a milling machine control unit as well as designing as simple as possible control laws. A two mass oscillator driven by a synchronous motor is used as test rig representing a x-axis device in milling machines. Experimental results are presented and compared with state of the art technologies. The μ-controller on the control unit is compared with cascaded PI-PI-control. For the Sliding Mode Controller the Robustness against varying nonlinear disturbance, i.e. Friction is compared to Model Based Friction Compensation. Copyright © 2007 IFAC. |
