摘　　要：提出了一种HSIC特征模型的改进算法(ICMA-HSIC),将系统动态过程划分为若干运行模态,与系统性能指标建立起直接联系,对系统响应做了完整的划分。在保证调节性能的前提下减少了调节参数的个数。采用闭环为主导的开环系统——闭开环控制结构,符合人类的思维。通过对二阶系统叠加不同的典型干扰信号,分析比较了闭环PID控制、ICMA-HSIC控制在不同的干扰作用下系统的动态、稳态性能的变化,仿真分析表明该控制方式具有较好的抗干扰能力。An improved characteristic model algorithm of HSIC was produced. This method divided the dynamic process of the system into five running mode, and built up relation with system performance directly. The adjuster parameters were decreased and didn’t influence the system performance. The control structure is open-closed-loop which the closed-loop is dominant and accords with human thoughtway. By adding various typical disturbance signals to the control channel in the two-order system, the analysis and comparison of the changes in the dynamic and steady performance of both the closed-loop PID control and the ICMA-HSIC were made. The results of the simulations show that the ICMA-HSIC possesses better performance of anti-disturbance.
