In this paper, an algorithm of a vaviable structure digital filter as a controller for the attitude control system of a bending vehicle is proposed. By means of the variable structure a superior frequency response is achieved in the frequency zone of the rigid body as well as in the frequency zone of bending modes, which provides an improved control effect. An example of an attitude control system of a bending vehicle is given. To show the merit of the new digital filter, the realization of the proposed...

To show the merit of the new digital filter, the realization of the proposed digital filter will not be diffcult due to its simplicity.

本文提出一种变结构数字滤波器作为弹性飞行器姿态控制校正装置。这种数字式校正装置的重要特点在于,借助于交结构,获得既对“刚体频段”,又对弹性频段都极为有利的频率响应,从而提供了改进的控制效果。文中给出了一个弹性飞行器的姿态控制系统作为设计举例。所建议的数字滤波器的实现是容易的。

Apply the theory of variable structure system to design an excitation controller. Pole placement method is used in the selection of hyperplane to simplify the design. This method is more convenient and with less computation than the method based on the quadratic performance index. Digital simulation indicates that the designed controller provides effective damping torque for power system and yields better system dynamic performance than that obtained by using linear optimal control.

根据变结构控制理论设计了励磁系统控制器。在开关超平面的选择上,采用了极点配置法,而不是基于二次型性能指标,从而减少了计算量,简化了设计。数字仿真结果表明,所设计的励磁控制器能为系统提供良好的阻尼,显著地改善系统的动态响应,而且其动态响应优于基于二次型性能指标的最优励磁控制。

A variable structure system (VSS) differs from a tradition automatic control system in that its structure is purposefully changed, in Jump-wise fasion, during the transient process, depending on the current values of the error signal and its derivatives. Introduced in this paper is the principle of design and analysis of VSS; and several essential advantages, such as high speed, insentiveness to variations in plant parameters and external disturbances, and simplicity of physical realization are pointed...
