在标准型双线性比例变结构系统循环进位控制的基础上，研究这种系统的比例—微分变结构控制。采用时间采样循环和状态变量循环的双进位控制算法，使系统的微分方程成为能分离变量和递推求解的一阶微分方程组。从减小系统失调误差的最终控制目的出发，提出了状态变量分量的步进置换概念。使用旋转算子表达比例—微分变结构的切换。用统一的时钟信号实现控制策略中的三种变换。给出了控制策略的结构图。

On the basis of cyclic carry control of variable structure system with standard bilinear proportion a variable structure with bilinear proportion differentiation is studied. Using calculation of double carry control of cycle for both time sample and state variable makes a differential equation of system be a group of first order differential equations which can be separated in variables and solved.With the last control purpose of reducing the error out control in system, the concept of step by step substitution for components of state variables is presented.A rotation operator is used to express the change of variable structure system with proportion differentiation.With the unified clock signals three kinds of changes in control design are realized.The structure diagram for the control design is shown.
