For non-proportionally damped linear systems the modal equations obtained from the undamped eigenvectors are coupled with the modal damping matrix. The non-proportional damping may be divided into two parts: the proportional part for dissipation of energy and the non-proportional

对于非比例阻尼线性结构体系,利用体系无阻尼实模态来形成模态响应方程时,得到的模态方程组是关于模态阻尼矩阵耦合的。非比例阻尼可以分成两部分:耗散能量的比例阻尼和转换能量的非比例阻尼。基于这种概念,本文采用了一种拟力实模态叠加法来求解非比例阻尼体系的动力分析,即把前述耦合模态方程中代表非比例阻尼的耦合项作为虚力,放到方程的右端,再运用迭代法进行求解。这种方法综合了经典模态叠加法和拟力法的优点。数值算例表明,此方法具有很好的收敛特性,所得结果精度高。我们认为,这种方法可应用于实际工程分析。

Most of papers about OCC(One-Cycle Control) only give the control equation by mathe-matic deduction,the physical meaning is not introduced,and why the output voltage Um of PI(Proportional-Integral) controller can reflect changes of load is still need deducted.The detailed steady state process of OCC APF(Active Power Filter) with both resistive load and nonlinear load is analyzed,based on which the physical meaning and steady condition of proportional part and integral part in PI controller are given.Proportional part and integral part have different functions:integral part dominates the big alteration of Um in long term,and it reflects load fluctuating;proportional part rectifies Um in a small extent and eliminates the harmonic current in each line cycle.The parameter design of PI controller is discussed and the design method of P parameter is given.Simulation results prove the rationality of the design method.

目前,关于单周控制理论(OCC)的研究一般仅以数学计算的方式给出OCC有源电力滤波器(APF)的控制方程,未阐明其物理意义,且用比例积分(PI)调节器的输出电压Um反映负载大小的合理性仍需论证。分别对纯阻性负载和非线性负载情况下OCCAPF的电路工作状态进行了详细分析。在此基础上给出了PI调节器中P和I环节的物理意义及其应满足的条件,发现可将其作用分开:I环节主导Um长期内较大的变动,用来反映负载大小的改变;P环节每个工频周期内对Um小范围调整,用来平衡每个工频周期内负载存在的谐波。讨论了PI调节器的参数设计,并具体描述了P参数的计算方法。仿真结果证实了该设计方法的合理性。
