摘要

提出了一种改进模型参考自适应控制方法的高阶系统控制方法。在实际可行的范围内,模型的传递函数是闭环系统期望传递函数的逆。通过调整系统,直到闭环系统的极点被模型的零点抵消,从而获得正常的运行。特殊的过滤器被设计来帮助检测这种抵消。它们有一个用于脉冲响应的窄脉冲,当脉冲应用于系统时,这个脉冲的色散被用作误差的度量。用于设计滤波器的准则是,它的脉冲响应应该有一个最小的第二矩,大约是最大的时间。将该方法应用于一个四阶螺距速率控制系统,并给出了计算机仿真结果。

A technique for the adaptive control of high-order systems
A technique which is a modification of the model-reference method of adaptive control is developed to handle high-order systems. The transfer function of the model is the inverse of the desired transfer function of the closed-loop system insofar as it is practically realizable. Proper operation is obtained by adjusting the system until the poles of the closed-loop system are canceled by the zeros of the model. Special filters are designed to aid in the detection of this cancellation. They have a narrow pulse for an impulse response and the dispersion of this pulse is used as the measure of error when an impulse is applied to the system. The criterion used for the design of the filter is that its impulse response should have a minimum second moment about the time of the maximum. The technique is applied to a fourth-order pitch-rate control system and the results of the computer simulation are given.
