Embodiment Construction

[0065] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0066] Such as figure 1 Shown is a control block diagram of an improved dual-port internal model control method suitable for unknown input tracking systems, which includes input and disturbance estimation loops, internal model controller G IMC (s), and common position controller C(s).

[0067] In order to realize the purpose of the present invention, the present invention provides a kind of improved dual-port internal model control method that is applicable to unknown input tracking system, and its method step is as follows:

[0068] Step (1): Through the sensor, directly obtain the tracking error signal of the unknown input tracking system;

[0069] Step (2): Perform a primary position closed-loop on the unknown input tracking system. After the primary closed-loop, the system characteristic is a low-pass filter, and the filt...

Abstract

The invention discloses an improved double-port internal model control method suitable for an unknown input tracking system, which is used for improving the tracking capability and disturbance suppression capability of the unknown input tracking system so as to meet higher-precision tracking control requirements. A standard dual-port internal model method requires input signals of a known system,so that the standard dual-port internal model method cannot be used in an unknown input tracking system. According to the improved dual-port internal model control method provided by the invention, the control effect of the dual-port internal model can still be realized under the condition that the input is unknown; and meanwhile, the tracking capability and the disturbance suppression capabilityof the system are improved. According to the method, the limitation of a standard dual-port internal model control method is broken through, the idea of internal model control is used under the condition that input is unknown, the tracking capacity and disturbance suppression capacity of the system are effectively improved, and the unknown input tracking system can obtain higher tracking precision.

Description

technical field [0001] The invention belongs to the field of tracking control, and in particular relates to an improved dual-port internal model control method suitable for an unknown input tracking system, which is mainly used to effectively improve the tracking ability and disturbance suppression ability of the unknown input tracking system when the input signal is unknown , to improve the tracking accuracy of the system. Background technique [0002] In the real world, there are many tracking systems that cannot know the system input, such as radar tracking systems, photoelectric tracking systems, etc. For example, "Research on Fast Tracking Method in Short-Range Multistatic Radar Detection System" (Xu Hongkui. [D]. University of Chinese Academy of Sciences. 2007), "Advanced Motion Control for Photoelectric Tracking System" (Ren Yan. [M]. Science Press Society. 2017), this type of system cannot obtain the input signal, and can only obtain the tracking error signal of the...
