摘　　要：为促进学生对解耦控制的深入理解,设计了基于Simulink的仿真实验,在设计方案无误的情况下,发现仿真结果与理论分析差异较大,这将可能误导学生对知识的理解。通过研究仿真架构在不同仿真条件下的响应结果的差异,发现Simulink在处理冲激响应时,不同的解算方法结果差异很大,进一步分析产生差异的原因。综合一些实际因素,提出改善的方法,即能保证解耦控制结果基本正确反映理论,也能对残留的误差找到符合逻辑的解释,使得理论内容与仿真结果达到统一。In order to enhance students’ understanding of decoupling control, a simulation case based on Simulink is designed. Under the correct design, the simulation result is quite different from theoretic result, which will mislead students’ understanding of knowledge. By studying the difference of response results of simulation architecture under different simulation conditions, it is found that the results of different solvers of Simulink are quite different in dealing with impulse response, and the reason of the difference is analyzed. Combined with some practical factors, a method to avoid such problems is put forward, which can ensure that the results of decoupling control basically reflect the theoretic result, and the remaining errors can be given a reasonable explanation. It makes the theoretical content be consistent with the simulation results.
