Energy-saving optimal control method and system of engine electric control silicone oil fan

Abstract

The invention provides an energy-saving optimal control method and system of an engine electric control silicone oil fan. The method comprises the following steps: vehicle operation environment data and engine internal operation data at the time k are acquired to build an overall operation state data set at the time k; a self-adaption dynamic planning system is built; self-adaption dynamic plan performance index functions at the time k, self-adaption plan efficiency functions at the time k and self-adaption dynamic plan performance index prediction functions at the time k+1 are calculated according to the overall operation state data set at the time k; the self-adaption dynamic planning system is dynamically optimized according to the performance index functions and the efficiency functions at the time k and the performance index prediction functions at the time k+1; iteration optimal control policies are obtained to output energy-saving optimal control signals to a silicone oil fan torealize dynamic energy-saving control of the rotating speed of the silicone oil fan; the self-adaption dynamic optimal adjustment of a controller is realized; the most optimal energy-saving control of the silicone oil fan is realized; and the life and the performance of an engine are effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of engines, in particular to an energy-saving optimization control method and system for electronically controlled silicon oil fans of engines. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] With the increasingly tense international energy supply and rising fuel prices, users have higher and higher fuel economy requirements for commercial vehicles. In order to ensure the normal operation of the engine, fans are essential. But the fan is also a consumer of engine power, the maximum is about 10% of the engine power, the electric silicon oil fan receives the signal from the engine electronic control unit ECU, adjusts the magnetic field of the solenoid, changes the magnetic field force, and thus changes the silicon oil circulation inside the silicon oil fan , so a...

Problems solved by technology

The above two general control methods do not take into account the external environment and load changes to adjust the controller parameters adaptively. At the same time, the silicone oil fan temperature adjustment system is a strong nonlinear dynamic optimization control system with large lag and large inertia. Artificial intelligence is not used. Technical insight into its internal dynamic operation coupling mechanism to establish a dynamic operation mechanism model of the silicone oil fan

[0005] Therefore, the current problems to be solved are as follows: (1) It is impossible to realize the adaptive dynamic adjustment of the silicon oil fan speed according to the environmental changes and load changes to achieve optimal control; (2) The large temperature fluctuation of the engine radiator seriously affects the service life of the internal combustion engine and performance and increased engine energy consumption
