摘　　要：分析了DEB400协调控制系统结构和控制原理,得出DEB400系统实际是对被控对象的非线性动态特性进行了补偿,这种补偿可改善广义被控对象的动态特性,部分消除由非线性造成的对象时间常数随负荷的变化,从而提高控制质量,利用MATLAB/SIMULINK仿真其广义被控对象动态特性及系统在扰动信号下调节量和被调量的变化,证明了这一结论.The paper analyzed the structure and control mechanism of the DEB400 coordinated control system, concluding that the DEB400 compensated the nonlinear dynamic characteristic of the controlled object, The compensation improves the dynamic characteristic of the generalized controlled object, decreases the variations of the object＇ s time constant caused by the changes of load, and by nonlinearity, hence the improvement of the quality of control. The Matlab-Simulink was used to simulate the dynamic characteristic of the generalized controlled object; the controlling and the controlled signal＇s dynamic behaviors with disturbance were also simulated. The simulations proved the correctness of the conclusion.
