The robust controller has good characteristic which can deal with disturbances and model errors. Especially μ-synthesis is a design method for the tradeoff between performance and robust stability, removing conservativeness due to unstructured singular values. We called the controller obtained by this method a μ-controller. However, it has the higher order generally. From a standpoint of cost and reliability, it is preferred that its order is reduced, which causes the degradation of the closed-loop performance. In order to decrease the degradation, it is necessary to take account the closed-loop configuration in the reduction process. For it, the authors developed the block balanced realization method in H∞ control. In this paper, we use the scaling matrix D obtained by the D-K iteration as frequency weights for the block balanced realization method. A numerical example is given to illustrate the effectiveness of our method. © 2009 The Institute of Electrical Engineers of Japan.

Design of nonlinear controllers tor active vehicle suspension with state constraints

Design of active vehicle suspension has tradeoffs between three main performance metrics (passenger comfort, suspension deflection and road holding ability). It has been known that each performance can be achieved by H ∞ . controller and they can be gathered by LPV (Linear Parameter Varying) method. However, because the suspension deflection limit was not explicitly considered, this limit may be exceeded. In this paper, the authors propose a "reference shaping" based method in order to improve the control performance. In this approach, a "virtual reference signal" is imposed to the system such that the suspension deflection is kept small. The effectiveness of the approach is examined by numerical simulations. ©ISAROB 2008.

In the literature, most of the stereo matching methods have been limited to gray level images, only few authors have dealt with color images straightly. In this paper, we propose a novel area-based color stereo matching method based on competitive-cooperative neural networks. Seven kinds of color spaces are tested in order to evaluate their suitability to stereo matching. The experimental results show that the matching precision is increased efficiently, when using adaptive color features instead of gray values.According to the experimental results, Ohta, Opponent and YCbCr color spaces can offer good color features for stereo matching. © 2005 IEEE.
