According to the characters of Dynamic Inversion method in making multivariable control system decoupling, we design a set of control law for every direct lift control mode.

本文针对动态逆控制方法的不足之处提出了相应的改善措施，并取得了较为理想的效果。

Variable air volume conditioning system is multivariable, strongly coupled, nonlinear and time variant, so its design, performance are more difficult than constant air volume conditioning system.

变风量空调系统具有非线性、多变量、强耦合及时变等特点，所以变风量空调控制系统的设计和运行的难度比定风量空调系统要大。

However since VWV system is multivariable, strongly coupled, nonlinear and time variant, its design performance and management are more difficult than constant flow chilled water volume system's.

但是变水量空调系统具有多变量、强耦合、非线性、时变的特点，其运行和管理相对于定水量系统难度大些。
