On hard and2-1 思考题：（1）数学模型的微分方程，状态方程，传递函数，零极点增益和部分分式五种形式，各有什么特点？（2）数学模型各种形式之间为什么要互相转换？（3）控制系统建模的基本方法有哪些？他们的区别和特点是什么？（4）控制系统计算机仿真中的“实现问题”是什么含意？（5）数值积分法的选用应遵循哪几条原则？答：（1）微分方程是直接描述系统

22、输入和输出量之间的制约关系，是连续控制系统其他数学模型表达式的基础。状态方程能够反映系统内部各状态之间的相互关系，适用于多输入多输出系统。传递函数是零极点形式和部分分式形式的基础。零极点增益形式可用于分析系统的稳定性和快速性。利用部分分式形式可直接分析系统的动态过程。（2）不同的控制系统的分析和设计方法，只适用于特定的数学模型形式。（3）控制系统的建模方法大体有三种：机理模型法，统计模型法和混合模型法。机理模型法就是对已知结构，参数的物理系统运用相应的物理定律或定理，经过合理的分析简化建立起来的各物理量间的关系。该方法需要对系统的内部结构和特性完全的了解，精度高。统计模型法是采用归纳的方法，根

23、据系统实测的数据，运用统计规律和系统辨识等理论建立的系统模型。该方法建立的数学模型受数据量不充分，数据精度不一致，数据处理方法的不完善，很难在精度上达到更高的要求。混合法是上述两种方法的结合。（4） “实现问题”就是根据建立的数学模型和精度，采用某种数值计算方法，将模型方程转换为适合在计算机上运行的公式和方程，通过计算来使之正确的反映系统各变量动态性能，得到可靠的仿真结果。（5）数值积分法应该遵循的原则是在满足系统精度的前提下，提高数值运算的速度和并保证计算结果的稳定。the principle of simplified EIA of construction projects in the
