This paper focuses on the load shifting problem in a household scenario with a large-capacity battery. We propose a novel Model Predictive control （MPC） framework to control the charge/discharge power of battery, hence to shave the peak load. Being different from other studies, the framework is designed on the base of individual habit of energy consumption, as it is envisioned that the individual habit is critical for choosing the suitable energy services. In this paper, the habit is modeled as a Markov process and gradually learned by an iterative algorithm;thus, the habit can be utilized for the prediction of future energy consumption. Then, the rolling optimization is applied for the optimal control of the charge/discharge power of battery. It is shown by numerical simulations that the proposed approach can significantly reduce the peak load.

Multi-Objective Load Distribution Optimization for Hot Strip Mills

Load distribution is a key technology in hot strip rolling process, which directly influences strip product quality. A multi-objective load distribution model, which takes into account the rolling force margin balance, roll wear ratio and strip shape control, is presented. To avoid the selection of weight coefficients encountered in single objective optimization, a multi-objective differential evolutionary algorithm, called MaximinDE, is proposed to solve this model. The experimental results based on practical production data indicate that MaximinDE can obtain a good pareto-optimal solution set, which consists of a series of alternative solutions to load distribution. Decision-makers can select a trade-off solution from the pareto-optimal solution set based on their experience or the importance of ob- iectives. In comparison with the empirical load distribution solution, the trade-off solution can achieve a better per- formance, which demonstrates the effectiveness of the multi-objective load distribution optimization. Moreover, the conflicting relationship among different objectives can be also found, which is another advantage of multi-objective load distribution optimization.

Studies have shown that applying a vibration of certain frequencies and intensities on the tooth can accelerate tooth movement, thus shorten orthodontic treatment *** optimal frequency may be related to the natural frequency of the tooth-periodontal ligament(PDL)-bone complex(TPBC),therefore we designed a vibrating device which can measure the natural frequency of the TPBC, and produce vibration load with customized frequencies and intensities. This device consists of four parts, vibration source, vibration frequency modulator,vibration amplitude modulator, natural frequency measurement module. To optimize the vibrator's design, specifically structure and natural frequency, static analysis and modal analysis were both made. The application method of the vibrator is also introduced. The designed vibrator can customize vibration load and obtain the natural frequency of TPBC, and it will be used for experiments to obtain the relation between the optimal frequency and the natural frequency of TPBC.

Memristor is a nonlinear resistor with the character of memory and is proved to be suitable for simulating synapse of neuron. This paper introduces two memristors in series with the same polarity (back-to-back) as simulator for neuron's synapse and presents the model of recurrent neural networks with such back-to-back memristors. By analysis techniques and fixed point theory, some sufficient conditions are obtained for recurrent neural network having single attractor flow and multiple attractors flow. At last, simulation with numeric examples is presented to illustrate our results.

An anti-windup compensate algorithm for active disturbance rejection mechanism is proposed in this paper. This paradigm extends the traditional anti-windup scheme to the Active Disturbance Rejection control(ADRC) mechanism, to deal with the input saturation nonlinearity and meanwhile reject the disturbance automatically by using Extended State Observer(ESO). The output of anti-windup compensator is treated as a part of unknown disturbances and is introduced into the ESO, which can online observe both internal and external disturbances(parameter uncertainties and model mismatches). The controller input is yielded by using a nonlinear feedback combination, and it is used to compensate the integrator windup caused by the saturation nonlinearity element. On the other hand, in order to determine the parameters of the ESO and the anti-windup compensator feedback gain, the L2 gain is adopted. The effectiveness and the robustness against model and parameter uncertainties of the proposed method is verified by an example of the seeker platform.

Introduction: Previous studies have shown that applying external vibrational load of a certain frequency and intensity can accelerate the tooth movement, thus shorten orthodontic treatment time. It is believed that the optimal frequency is correlative to the modal mode of the target toothperiodontal ligament(PDL)-bone complex(TPBC). This study aims to investigate modal mode, natural frequencies included,of the TPBC using finite element(FE) method. Methods: A three dimensional TPBC model of a maxillary central incisor were reconstructed from cone beam CT images. A FE model was then created in Ansys 14.5. The tooth, PDL, and bone were meshed with 10-node hexahedral elements(SOLID 187)with the numbers of the elements equaled to 17,803, 4,137,and 32,577, respectively. All parts were considered homogeneous and isotropic. The material properties(Young's Module(Pa),Poisson's ratio and Density(kg/m3) as: 2e10, 0.31 and 1.36e3 for tooth, 4.7e5, 0.4 and 1.1e3 for PDL, and 3.5e9, 0.33 and 1.4e3 for bone, respectively. Fixed constraint was set for the alveolar bone. PCG Lanczos method was used in the modal *** order modes were included in the computation. Result:The first six order modal mode of the TPBC were *** corresponding natural frequencies were 702, 1049, 2713,2805, 3026, and 3530 Hz, respectively. Different tooth movement patterns, including translation, rotation, extrusion/intrusion,were observed in these modal modes. Conclusion: The proposed method is able to obtain the natural frequencies and modal modes of a TPBC. The results can be used as reference for developing vibrational device to accelerate orthodontic tooth movement.

This paper proposed a boundary feedback control design for open-channel networks with trapezoidal cross sections by using a Riemann invariants approach. The open-channel network is well modeled by the nonlinear Saint-Venant equations. Based on the characteristic form in terms of Riemann invariants, the stabilizing boundary control is developed for a single canal. The stability condition and the boundary control design are subsequently generalized to open-channel networks composed by multireaches in cascade. The design of the boundary feedback control laws either for a single canal or for the cascaded networks is illustrated in a unified design framework. © Springer-Verlag Berlin Heidelberg 2013.
