摘　　要：介绍了混合逻辑动态(MLD)系统及其预测控制的优化问题,使MLD系统在满足操作约束的情况下能稳定在期望的稳态值上,同时尽可能地考虑用启发规则表示的定性知识。根据混合逻辑动态系统的标准形式,转化为混合整数二次规划(MIQP)的问题,同时获得它的数学描述。应用相应的混合整数二次规划解题器实施滚动优化技术,在参量可以调整的情况下,得到较好的控制效果。并以三槽水位模型(混合逻辑动态系统的Benchmark问题)作为仿真实例,仿真结果表明了预测控制的良好性能。The mixed logical dynamic system (MLDS) and its predictive control are introduced, which can stabilize MLDS on desired reference trajectories while fulfilling operating constraints, and possibly take into account previous qualitative knowledge in the form of heuristic rules. According to the standard form of MID system, the problem of mixed integer quadratic programming (MIQP) and its mathematics description can be obtained. So it is available to utilize MIQP solver to apply to the technology of horizontal optimization where the parameter can be adjusted to get better performance. Three-tank system is taken for example. The results show the good performance of the predictive control.
