Application of Centralized and Decentralized Control to Building Structure: Analytical Study

This paper presents both the centralized and decentralized control strategies by using semiactive control devices (magnetorheological dampers) for building structural control under seismic excitations. The control algorithms used in this study only focus on the linear quadratic Gaussian control theory with acceleration measurements as feedback signals. In the centralized control, the control force is generated directly from the measurement in each degree of freedom, while in the decentralized control, only measurement from local subsystems is used to calculate the control force with respect to the locations of control devices and measurements. Four groups of centralized/decentralized control algorithms are studied: fully centralized control, fully decentralized control, half-centralized control, and partially decentralized control. The ASCE 20-story benchmark building is selected as an example to evaluate the control performance among different control strategies.

Longitudinal analysis of specific domains of internal control and depressive symptoms in patients with recurrent cancer.

The relation between perceptions of control and depressive symptoms was examined in a longitudinal study of patients with recurrent cancer. Five domains of control (self-blame, control over cancer onset, control over symptoms, control over the course of the illness, and overall control over life events) were found to be independent of one another. In cross-sectional analyses, depression symptomatology was negatively correlated with illness course control, symptom control, and overall control. Cross-lagged longitudinal analyses using structural equation modeling suggested only onset control and overall control were significantly associated with depressive symptomatology over the 8-month interval. Greater baseline onset control predicted greater follow-up depression, whereas higher baseline depression predicted lower follow-up overall control. The importance of developing and using domain-specific measures of control and investigating the association of control and adjustment in longitudinal analysis are discussed.

Primary and secondary control over age-related changes in physical appearance

Beliefs about appearance-related changes due to aging were used to test the effects of perceived control and secondary control (acceptance) in a sample of 412 young, early-middle-age, and late-middle-age college-educated adults. Mean difference in aging-related appearance control and hypotheses regarding the adaptiveness of primary and secondary control were examined. Primary control over aging-related appearance was lower in older adults and secondary control was higher. In addition, the results indicated support for the Primacy/Back-Up Model that primary perceived control is important at all levels of actual control. Those with stronger beliefs in their primary control were less distressed. Secondary control served a back-up function in that it was related to less distress only for those who had medium or lower beliefs in primary control. The implications of these findings, that primary control may be advantageous even in low-control circumstances, are discussed.

广义预测控制在泵池回路中的应用

广义预测控制融合了预测控制和自适应控制的优点,是自适应控制中另一类型的预测控制方法,易于在线估计参数,以实现自适应控制。磨矿生产中,泵池回路控制是一个复杂的慢时变动态过程控制,具有很强的非线性、强耦合、大滞后、强干扰等特性,而传统的PID控制算法很难达到理想的控制效果和较高的自动投运率。为此,针对泵池控制回路的特点,提出基于模型性能指标和加权系数的广义预测控制算法,建立了泵池控制模型,并于2010年将该模型应用于金川选矿厂磨矿生产的泵池回路控制。实际工业应用表明,这种广义预测控制具有较强的适应性和较高的控制精度,控制效果优于传统PID控制算法。
