求解简单振动系统的响应（中心差分法，Wilson-θ法，Newmark-β法，Houbolt法）(Solving simple vibration response of the system (central difference method, Wilson-θ method, Newmark-β method, Houbolt method))

对精馏塔的工艺流程精馏段温度TR和提馏段温度TS控制，以确保塔顶和塔底产品的质量，所设计的解耦控制系统仿真图。(The distillation process, distillation temperature, TR and stripping temperature TS are controlled to ensure the quality of the products at the top of the tower and the bottom of the tower. The simulation diagram of the decoupling control system is designed.)

A Matlab toolbox for exact linear time-invariant system identification is presented. The emphasis is on the variety of possible ways to implement the mappings from data to parameters of the data generating system. The considered system representations are input/state/output, difference equation, and left matrix fraction. KEYWORDS: subspace identification, deterministic subspace identification, balanced model reduction, approximate system identification, MPUM.
