This paper considers the problem of reliable control for a class of uncertain switched system via sliding mode control technique. By means of a matrix transformation, a common sliding surface is designed. Moreover, the asymptotical stability of the sliding mode dynamics is analyzed by adopting the multiple Lyapunov functions method based on the min-projection strategy. Besides, the state trajectories can be driven onto the proposed sliding surface despite the presence of the parameter uncertainties and the actuator faults. The efficiency of the controller design is demonstrated by a numerical example.

In this paper is developed cascaded non-linear sliding modes control (SMC) to ensure the flux-speed tracking regime of voltage fed induction machine. The control law is derived in two steps by exploiting back stepping methodology. In the first the virtual SMC, based on Lyapunov function, is derived in view to enforce the flux-speed tracking. Thereafter, is deduced the real sliding modes control imposing the virtual SMC law. The simulation results of flux-speed tracking of induction machine show the validity of the proposed method in presence of strong disturbances.

Cloud computing provide an efficient big data processing platform for many small and medium scale enterprises, how to replicate and allocate data in clouds is a critical problem influencing cost consumption for small and medium scale enterprises. Cloud data management systems mainly serve two kinds of workloads, one is read-intensive analytical workloads (e.g. OLAP), the other is write-intensive transactional workloads (e.g. OLTP). It is essential to minimize data management costs like storage, communication bandwidth, update and power with guaranteeing the service level agreements. Toward two workloads, a cost-effective data replica placement approach for minimizing data management costs on cloud computing centers is proposed. The definition of different data management costs is identified first, then we construct the cost optimization model of the data replica placement problem. The paper proposes a hybrid genetic algorithm and a data support-based initialization method that addresses the problem. Experiments show that the approach result in significant reduction in total data management cost and the algorithm is with good performance. © IFIP International Federation for Information processing 2018.

Multiway principal component analysis (MPCA) has been successfully used to monitor batch processes. But, there exist two problems when MPCA is used to monitor batch processes. One is that the process data must submit normal distribution. Another is that MPCA need complete batch data for online monitoring, so the values from the current until the end of its operation must been estimated or filled in. To overcome those problems, a novel monitoring method, multi-model discriminant partial least squares (multi-model DPLS), is presented. The proposed method is proved to be effective by the application of an industrial streptomycin fermentation process. © 2005 IEEE.

Linear Quadratic design for the fault tolerant control of the short-period mode of the longitudinal model of the Boeing 747 aircraft is investigated. Under actuator faults, both fault accommodation and system reconfiguration procedures need the controller to be re-designed, which means solving the Algebraic Riccati Equation (ARE) associated with the post-fault system model. To overcome the risks of system instability and/or control inadmissibility, which result from fault detection and isolation delay, and computation time of the accommodated control, a progressive accommodation strategy, based on the Newton-Raphson algorithm for solving AREs, is used. The application shows the benefits associated with this approach.

In this paper, we present an approach for haptic object recognition and its evaluation on multi-fingered robot hands. The recognition approach is based on extracting key features of tactile and kinesthetic data from multiple palpations using a clustering algorithm. A multi-sensory object representation is built by fusion of tactile and kinesthetic features. We evaluated our approach on three robot hands and compared the recognition performance using object sets consisting of daily household objects. Experimental results using the five-fingered hand of the humanoid robot ARMAR, the three-fingered Schunk Dexterous Hand 2 and a parallel Gripper are performed. The results show that the proposed approach generalizes to different robot hands. Keywords: Object Recognition, Bag of Keypoints, Robot Hands, Tactile Sensing. © 2012 IEEE.

39th IEEE Confernce on Decision and control

作者： Haiqing, W. Zhihuan, S. Ping, L. Natl. Lab. Indust. Control Technol. Inst. of Industrial Process Control Zhejiang University Hangzhou 310027 China

process monitoring and fault diagnosis using principal component analysis (PCA) were studied intensively and applied to industry processes. The emphasis of most PCA-based works has been mainly on procedures to perform monitoring and diagnosis given a set of sensors, and little attention is paid to the actual location of sensors for efficient detection and identification of process faults. In this paper, graph-based techniques are used to optimize sensor locations to ensure obtaining the maximum fault resolution. Based on the optimized sensor network, an improved PCA is proposed by introducing two new statistics of PVR and CVR to take place the Q statistic in the conventional PCA. The improved PCA can efficiently detect weak changes, and give an insight into the root cause of process fault. Simulation results of a CSTR process show that the improved PCA with optimized sensor locations is superior to the conventional methods.
