In order to improve the tracking performance, the scaling factors of FLC are searched by genetic algorithms (GAs). The simulation results show that all three control approaches, SMC (sliding mode control), FSMC (fuzzy-SMC) and GA-FSMC (GA-based FSMC) can stabilize the mobile robot to the origin with /spl phi/=0. However the GA-FSMC provides a systematic way to search the scaling factors, and thus improves the transient performance of the system response and reduces the path length for navigation.","PeriodicalId":197019,"journal":{"name":"Soft Computing in Intelligent Systems and Information Processing.

An ultrasound transducer is often used as the heating device. In order to kill the tumor cells and not injure the normal tissue, the temperature distribution generated by the ultrasound must be predetermined. For a multi-element ultrasound transducer, the phase and the amplitude of the input signal for each element can be tuned to generate a suitable temperature distribution to meet the needs of individual treatments. However, direct computation is often time-consuming, while there are also difficulties in computing the ultrasound transducer parameters with a given temperature distribution. In this paper, artificial neural networks are used to learn the relationship between the ultrasound transducer parameters and the temperature distribution, both in the forward and in the inverse direction.","PeriodicalId":197019,"journal":{"name":"Soft Computing in Intelligent Systems and Information Processing.

The study focuses on the prediction of future trends of the 90 to 180 day commercial paper interest rate. The outcome shows several encouraging messages: (1) While the result of applying the multiregressional model on this kind of problem is awkward, the improved backpropagation networks, especially the one integrating Nguyen-Widrow Method and Adaptive Learning Rate Method have good performance without involving the serious problems of multicollinearity and autocorrelation. (2) With small tolerance error, the network forecasting reliability is satisfactory no matter whether random or moving simulation sampling is adopted. (3) For avoiding the impact of random wave, we take the average daily interest rate t-2,t-1,t+1,t+2 as the target output. In so doing the network presents a good learning effect with the accuracy of forecast beyond 98%. (4) The performance of the improved backpropagation network like momentum is not always better than a pure backpropagation network. We learned from the study that the fluctuating trend of interest rate may be influenced by different combinations of economic and monetary independent variables in different time periods, so rashly gathering a big sample without reviewing the attributes of the data may prevent the authentic forecasting effect of the network.","PeriodicalId":197019,"journal":{"name":"Soft Computing in Intelligent Systems and Information Processing.

We propose a performance-based adaptive aggregation for modular controllers. Conventional modular control techniques, like decentralized control, singular perturbation and hierarchical decomposition, use non-adaptive aggregation and are only applicable to a restricted class of nonlinear systems. It is demonstrated in this paper that adaptive aggregation extends the validity and the performance of a modular design to a wider class of nonlinear systems. Rule-based aggregation, induced by fuzzy logic and rough sets, is proposed for ease of design and utilization of a priori knowledge. The emphasis in this paper is on model-independent design.","PeriodicalId":197019,"journal":{"name":"Soft Computing in Intelligent Systems and Information Processing.
