Document Type and Number:
WIPO Patent Application WO/2020/177269
Kind Code:
A1
Abstract:
An adaptive control parameter adjustment method for a BBMC asynchronous electric motor speed regulation system, the method comprising the following steps: by taking control parameters of finite time control as optimization objects and taking an output voltage harmonic distortion of a Buck-Boost matrix converter (BBMC), a capacitor voltage deviation signal and an output current deviation signal as optimization targets, establishing a mathematical model between the optimization targets and the optimization objects; establishing a multi-target optimization satisfaction function and a multi-target optimization fitness function; carrying out iterative optimization on the control parameters of the finite time control by means of an adaptive wolf pack optimization algorithm to obtain n groups of optimal finite time control parameters; and obtaining a functional relation between the optimal control parameters and the actual output current of the BBMC by using a numerical fitting method, and determining, according to the obtained functional relation, an optimal control parameter corresponding to any load of a speed regulation system. By means of the method, control parameters can be adjusted in real time according to an obtained functional relation, that is, according to the size of the load of the speed regulation system, namely, the magnitude of the actual output current of a BBMC, so that the speed regulation system can achieve the best operation effect under any load.
