Abstract

The invention relates to a fuzzy control method of a bench control system, a storage medium and computer equipment. The fuzzy control method mainly comprises the following steps: acquiring a historical data set; clustering the historical data set by using an FCM algorithm, obtaining a value of a data densest region in a clustered historical data subset as a maximum value of a membership function, and dividing the historical data subset into a fuzzy set by using the membership function; constructing a fuzzy control model based on a Wang-Mendel algorithm; acquiring expert experience data as training data, and training the fuzzy control model by adopting a supervised learning method; inputting the fuzzy set into the trained fuzzy control model to obtain a fuzzy rule set; defining fuzzy rules with different conditions in the fuzzy rule set as proximity rules, and complementing incomplete fuzzy rules in the fuzzy library by using the proximity rules to obtain a new fuzzy rule set; and inputting the new fuzzy rule set to the rack control system to carry out PID parameter self-tuning.

Description

technical field [0001] The invention belongs to the technical field of automobile engine-dynamometer bench, and in particular relates to a fuzzy control method, storage medium and equipment of a bench control system. Background technique [0002] The engine bench test is an important method and means to analyze and evaluate the various performance indicators of the engine by simulating the operating characteristics of the engine under different working conditions (load, speed) and recording various test parameters. In the bench test, it is necessary to precisely control and detect the main parameters of the engine and dynamometer, such as speed, torque, engine throttle opening, excitation, etc. At the same time, a large number of parameters in the test, such as fuel consumption, engine multi-point intake and exhaust The temperature, pressure, oil temperature, water temperature and exhaust emission are tested, and various key data and curves of the engine are obtained through...
