Abstract

The invention provides a target air inlet density control method, device and equipment and a readable storage medium. The target air inlet density control method comprises the steps that the initial target air inlet density is obtained; based on a PI control method, the target air inlet density of the P item is obtained through calculation; the target air inlet density of the I item is determined; summation calculation is conducted on the target air inlet density of the P item and the target air inlet density of the I item, and the optimized target air inlet density is obtained; the optimized target air inlet density is limited, and the final target air inlet density is obtained; and the final target air inlet density is used for controlling the opening degree of a throttle valve. According to the method, the final target air inlet density is used for controlling the opening degree of the throttle valve, due to the fact that the throttle valve is high in control precision and free of response delay, the target air inlet density can be efficiently achieved through the throttle valve, and dynamic closed-loop control adjustment is formed between the target air inlet density and the actual air inlet density; and the time lag problem of the air inlet system of the engine is well solved.

Description

technical field [0001] The present invention relates to the technical field of engine control, and in particular, to a method, device, device and readable storage medium for controlling a target intake air density. Background technique [0002] The engine intake system transmits atmospheric gas to the cylinder, the intake system is complicated to bend, and the engine operating conditions change rapidly, resulting in a delay in the response of the air volume control of the intake system. As a common feature of industrial controlled objects, time delay is very To a large extent, it restricts the control effect of the engine air intake control system. Therefore, it is necessary to correct and adjust the target intake air density in real time. The control accuracy of the throttle valve is high, and there is no shortcoming of response delay. Therefore, it can be adjusted through the throttle valve. The valve realizes efficient control of the intake air volume. [0003] Among the...
