This paper investigates the Robust model predictive tracking control for constrained networked control systems with Markovian packet dropout. By introducing a packet dropout compensation strategy and an augmented Markov jump linear model with polytopic uncertainties, the effects of data loss on the system performance are considered simultaneously. Input, and output constraints are also incorporated into the model predictive control. Furthermore, both the recursive feasibility of the proposed MPC algorithm and the closed-loop mean-square stability are proved. A numerical example is given to illustrate the effectiveness of the controller.

为促进光伏组件回收产业快速发展,优化现有光伏组件回收政策结构和效应。基于对光伏组件回收相关文献和政策的分析,从生命周期理论视角,通过编制光伏产品碳足迹核算边界图,观察产品碳足迹,梳理分析光伏组件回收过程中碳指标政策现状及困境,探究挖掘碳指标政策优化方案及策略。结果表明:近年来,各级政府针对光伏组件回收制定不少政策,取到了引导和支持作用。但是光伏组件回收碳指标政策不健全、碳指标数据系统未建立、碳资产管理机制缺失、碳经济效益未兑现等深层次问题依然存在。基于研究结果提出构建光伏组件回收碳数据追溯监管体系、碳指标分布式体系、碳资产管理体系、碳指标奖惩体系、碳指标评估体系等策略,发挥碳指标在各方利益主体中政策杠杆作用,完善光伏组件回收政策体系,推动光伏产业可持续发展,减少环境污染和资源浪费。

Time-delay of magnetorheological elastomer bearing(MRB) can bring structural response menace to bridges. This paper investigates a bridge pier-bearing semi-active-coupling control method based on model predictive control(MPC). The presented strategy takes the structure prediction model to predict the state responses of the controlled plant in a period of future time. Then, the control law can be determined by solving a finite horizon optimization problem. The peak shearing force of pier top, the displacement and the acceleration of beam are chosen as control goals, and the vibration isolation rate is applied to characterize the vibration isolation *** is noted that MPC method naturally takes the time-delay and uncertain interference into consideration, and significantly improves the control performance of the system. Finally, the numerical example is described and the seismic response of isolated bridge based on MRB is analyzed. The simulation results show that predictive control can be used to control the time-delay of bridge system in different degrees. The best control performance is at0.4 s. Even if the time-delay reaches 2 s, it is still good. Therefore, the control method significantly reduces the adverse effects of time-delay on the system, and has a good vibration isolation performance.

It is usually difficult to measure acoustic velocities through a casing, especially when the casing is poorly bonded with formation. An acoustic logging technique using the dual source of opposite polarity is proposed to enhance the Signal to Noise Ratio of the formation signal and to reduce the casing wave in the data acquisition process. In what follows, a theoret- ical modeling is used to caculate the wavefroms of cased wells. And then, a scaled experiment was conducted in the 1：10 scaled experimental well using the proposed technique in the poorly- bonded condition. The results show that this technique can effectively suppress the casing wave and enhance the formation wave, even in the poorly-bonded condition. By analyzing the measured wavefroms, the amplitude of casing wave is reduced to 12% compared to the conventional one-source technique, and the compressional wave velocity can be easily obtained by using this technique. Both the theoretical modeling and experiment results demonstrate the feasibility of the proposed technique. This study establishes the theoretical and experimental foundation for the cased-hole, dual source of opposite polarity, acoustic logging tool development.
