Embodiment Construction

[0040] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0041] At present, the existing ITAE optimal system only considers Type III and systems below Type III. The higher the type, the higher the static error degree and the better the tracking performance. However, it is more difficult to realize the ITAE optimal system than Type III. very big.

[0042] The present invention proposes a realization method of ITAE optimal N-type system based on ESO. The Extended State Observer (ESO) is the core part of the active disturbance rejection control technology. Observed as a total disturbance and compensated at the input, it can be systemized as a standard series integrator. Both theoretical research and practical engineering have proved that ESO can greatly simplify the controlled object and make the control law design easier. The invention utilizes that ESO only needs very little model information, and also has the ...

Abstract

The invention discloses a construction method of an ITAE (Integral Time absolute error) optimal N-type system, and relates to the field of signal tracking and control. According to the method, an extended state observer is introduced into a multi-target optimized ITAE optimal control system, so that the implementation process is simplified, the ITAE optimal control system of which the type exceeds type III is realized in engineering, and the anti-interference capability of the ITAE optimal control system is enhanced.

Description

technical field [0001] The invention relates to signal tracking and control, in particular to a method for constructing an ITAE optimal N-type system. Background technique [0002] A good position servo system not only needs to have a good step response, but also needs to have a good position tracking performance. In order to achieve a higher order of no static error, it is necessary to increase the number of integrators included in the open-loop transfer function, at the cost of the system tends to be unstable, and the difficulty of controller design increases. [0003] ITAE is an index to measure system performance, and the objective function is [0004] J ( I T A E ) = ∫ 0 + ∞ t | e ( t ) | d ...
