摘　　要：针对注塑成型过程中的主要阶段注射段与保压段,提出了最小运行时间控制方法,在保证控制系统性能基础上使运行时间最小。考虑注射段与保压段系统模型维数不同,将注射段与保压段看做一个不同维切换系统并将其转化为等价二维系统。利用平均驻留时间方法,在二维系统理论框架内,研究系统指数稳定与最小运行时间问题。仿真结果证明所提出方法的有效性与实用价值。Aimed at the filling and packing-holding phase of injecting modeling,a novel minimum running time method was proposed,meanwhile,the control performance was guaranteed. The filling and packing-holding phase were treated as a different dimensional switched system considering that the model of the two phases are different dimensional and were transformed into an equivalent two-dimensional (2D)system. Under 2D system framework,the exponential stability and minimum running time problems were studied by using an average dwell time method. Simulation demonstrated the effectiveness and merits of the proposed method.
