Abstract

The invention discloses a variable parameter control method of a sine instruction. According to the invention, real-time determination is carried out on frequencies and amplitudes of an instruction signal of a sine instruction control system; after a certain operation period, when processing on the frequencies and the amplitudes of the sine instruction is completed, adjustment is carried out on coefficients of a proportional P and a differential term D of an integration separation PID algorithm according to different frequencies and amplitudes, so that a control algorithm of a variable parameter is realized and thus a high control precision of the system is reached. According to the invention, a problem on an amplitude frequency response characteristic of a servo system in a wide range isresolved; moreover, a principle employed in the invention is simple and practical as well as reliability is high.

Description

technical field [0001] The invention relates to a parameter control method, in particular to a sine command variable parameter control method. Background technique [0002] The sinusoidal command signal is a common command type in the servo control system, and it is widely used in the servo control of the weapon system. The PID control method is simple, robust, and highly reliable. It is the most widely used control method at present. However, in the actual application process, the control object generally has nonlinearity and time uncertainty. When the amplitude-frequency range of the sinusoidal command signal is large When the frequency is wide, the conventional non-variable parameter PID control method is difficult to achieve the ideal control effect in the whole frequency range because the control parameters are fixed values. For intelligent control methods such as fuzzy PID, its algorithm implementation and parameter adjustment are relatively complicated, and the amoun...
