Abstract

Close
- Recently, a data-driven model-free iterative control design method has been proposed [Hjalmarsson et al., Proc. 33rd IEEE CDC, Orlando, FL, 1994, 1735–1740]. This design method works directly with closed loop data from the plant and iteratively improves the pelformance. This contribution reports a simulation study of this method when applied to a flexible transmission system. The system is characterised by load dependent dynamics and certain performance specifications have to be satisfied for three different load cases. These specifications cannot be translated into a specific control criterion a priori. However, by adaptively changing the design criterion it is shown that it is possible to tune the criterion so as to eventually obtain the desired closed loop performance for all three load cases with the same controller. The new concepts of synthetic noise and time delays are shown to be valuable tools when tuning the criterion.
