PID controller has simple structure and easy applicability with strong performance robustness. Decentralized PID controller and decoupling PID controller are widely adopted in the control of two-input-two-output (TITO) processes. Firstly, a simple decoupling controller matrix and a desired dynamic decoupling controller matrix are designed according to the idea of coupling matrix. And then three schemes of controller including decentralized PID controller, simple PID decoupling controller and desired dynamic PID decoupling controller are provided based on the excellent characteristic of DDE. Lastly, the Monte-Carlo stochastic experiment is introduced to analyze performance robustness of the controllers. The simulation experiments illustrate that the simple decoupling control scheme has the ability of complete decoupling and better performance robustness.

This paper tackles the regulation problem of linear time invariant systems with unmatched perturbations. The proposed methodology exploits a high order sliding mode observer, which guarantees theoretically exact state and perturbation estimation. In this work is introduced a controller with a compensation strategy based on the identified perturbation values. A nested backward sliding surface design is proposed, which allows to compensate the unmatched uncertainties and to stabilize some of the non-actuated state components, while all the remaining states are maintained bounded. The overall stabilization error is estimated in terms of the sampling time and actuator time constant values. The feasibility of the technique is showed in a rotary inverted pendulum simulation example.

Active yaw stabilization for passenger vehicles, following driver yaw rate commands with steer-by-wire and rear break force distribution, is discussed. The problem is solved via a decomposition of the vehicle equations of motion into a static, scheduled tyre characteristics map, and an affine Linear Parameter Varying (LPV) plant. control is provided via a cascade connection of scheduled inverse tyre characteristics and an LPV controller, handling both the nonlinear dynamics an the non-affine tyre characteristics. Excellent tracking results are demonstrated with a high fidelity simulation even in the presence of noise and uncertainty. © 2009 EUCA.

In this study, the multivariate probability distribution was investigated to develop the expert knowledge-based automatic sleep stage determination technique. The ultimate purpose is to develop adaptive automatic sleep stage determination algorithm for clinical practice. Gaussian distribution was adopted to realize automatic parameter selection while Cauchy distribution was adopted to estimate the parameter distribution. The different usage of multivariate probability distribution of Gaussian and Cauchy distribution presented effectiveness for automatic sleep stage determination. © 2009 SICE.

The paper presents a joint state and unmeasured input estimation technique for a special class of nonlinear second order macroscopic traffic model. The freeway traffic system is transformed into a quasi and affine approximate Lin- ear Parameter Varying (LPV) form. Observer design technique is formulated using off-line optimization problem subjected to Linear Matrix Inequality (LMI) conditions, considering uncertain scheduling parameters. Furthermore, locally designed state estimators are interconnected to cover multiple freeway sections. The elaborated method is validated using real traffic measurements. © 2009 EUCA.

SICE Annual Conference

This paper will present a study on the robustness of anti-windup systems where the plant uncertainty can be expressed by LTI norm-bounded operators. The treatment is constructed under the IQC framework of Megretski and Rantzer. Robustness of anti-windup systems against LTI uncertainty using frequency dependent IQCs are less conservative than those where plant uncertainty is addressed by static IQCs. They can however increase significantly the computational burden in the algorithms. The paper shows that sufficient conditions for robustness of anti-windup systems against LTI uncertainty can be, in some circumstances, greatly simplified. They can also be expressed in the frequency domain and interpreted graphically. The test is finally exploited for anti-windup tuning.

IEEE International Conference on Networking, Sensing and control

A new type of data-driven control framework for non-Gaussian stochastic systems is established in this paper. Different from the traditional feedback style, the driven information for tracking problem is the statistic information set (SIS) of the output rather than the output value. The set of statistical information (including the moments and the entropy) or probability density functions (PDFs) of the output are the measured information and the controlled objective. Under this framework, a mixed two-step adaptive neural network (NN) modeling is established with combining a static NN for description of the statistic information or PDFs and a dynamic one for identification of the relationship between input and output weight vectors. An adaptive PI tracking controller based on the proposed dynamic NNs is designed so as to track a target stochastic distribution. Finally, simulation results on a model in paper-making processes are given to demonstrate the effectiveness.

Quantitative analysis and detection of abnormalities for electroencephalogram (EEG) recordings during evoked activities are essential for clinical diagnosis on neurological disorders. However, the process of interpreting EEG is time consuming and requires experienced electroencephalographers (EEGers). In this study, a method of automatic EEG interpretation during hyperventilation was proposed. The purpose is to provide a quantitative interpretation of EEG which is able to conform to EEGers' visual inspection. The final integrated results of automatic interpretation were compared with EEGers' evaluation, and showed high consistence. © 2009 SICE.
