52747 为了保证经济性能指标发生改变后CFBB燃烧过程在稳态工况下的稳定性和燃烧经济性，首先引入关于最优经济稳态点的正定辅助函数作为最高优先级目标， In order to ensure the stability of the CFBB combustion process under steady-state conditions and the economy of combustion after the economic performance criterion changes, the positive definite auxiliary functions at the optimal economic steady-state points are introduced and viewed as the highest priority goal,
52748 其次考虑床温设定值跟踪目标和经济性目标。 and then the set-points tracking target of the boiler bed temperature and the goal of combustion economy are considered.
52749 进一步，应用广义终端约束、字典序多目标优化和滚动时域控制原理，设计CFBB燃烧过程变经济性能多目标经济预测控制器。 Furthermore, applying the generalized terminal constraints, lexicographic multi-objective optimization and predictive control principles, a multi-objective model predictive controller with changing economic performance is designed for CFBB system.
52750 最后，通过仿真验证了本文提出策略的可行性和有效性。 Finally, the feasibility and effectiveness of the strategy proposed in this paper are verified by simulations.
52751 在无中心Web服务环境中，用户访问服务的历史行为数据由多个服务提供方分散管理，难以形成全局的用户信任度视图，难以根据用户信任度和使用需求实施个性化的访问控制。 Trust based dynamic access control(TBAC) is one major technique on protecting service providers'(SPs)resources. The personalized access control and the reliability of trust are the central problems of TBAC.
52752 本文提出一种基于智能合约的个性化访问控制方法(SC-PAC)。 To solve it, this paper proposes a smart contract based personalized access control method(SC-PAC).
52753 通过结合前期的研究成果为SC-PAC提供高质量的用户历史行为数据，实现有可靠数据保障的可信计算服务， Combined with the previous work, reliable behavior data of users are provided to ensure a reliable trust evaluation.
52754 通过智能合约中的策略配置及可信度计算模型参数调整，实现服务提供商(SP)对不同用户的个性化的访问控制。 It introduces a smart contract-based access control procedure, which allows SPs to flexibly set the trust model, parameters, and the access control policies, to provide a customer-level personalized access control.
52755 在实验环节为SC-PAC设计了一个新的信任模型，并对该信任模型及基于SC-PAC方法的访问控制进行了实验设计。 A new trust model is designed in case study and experiments are designed to test this trust model and the SC-PAC method.
52756 对结果的分析表明，本文提出的SC-PAC方法能够允许SP通过智能合约中的计算信任模型、参数及访问控制策略选择，实现对用户的个性化访问控制，并且依据准确的用户历史行为数据提供更可靠的可信度判断，可以有效保护服务。 The results of experiments show that the SC-PAC can provide a customer-level personalized access control compared with the traditional work and a more reliable trust evaluation through the accurate behavior data of users.
