Example Embodiment

[0017] The first embodiment is an engine power compensation system for an air vehicle. The input device transmits the gear signal, key signal, and air flow signal to the ECU controller, and the ECU controller controls the air storage device to output air to drive the aerodynamic motor, Further driving the car forward, it is characterized in that the aerodynamic motor also calculates a flow compensation signal through a logarithmic circuit.

Abstract

The invention discloses an engine power compensation system of an air vehicle; a logarithmic circuit is used for applying a natural logarithm operation circuit to perform natural logarithm operation solving on a flow signal and an expected flow signal which are measured by a flow sensor and enter an air power motor separately; a division operation is carried out through a divider IC1 under the control of a synchronous switch, and a flow signal needing to be compensated is directly obtained; the circuit structure is simple, and the calculation is accurate; a signal coupling circuit receives a flow compensation signal and converts the flow compensation signal into a signal for driving a flow valve through a proportional amplification circuit with feedback, then the signal enters an operational amplifier AR5 and is coupled with the fed-back flow signal, and then is subjected to amplitude limiting and filtering after voltage stabilization, and then is output to the grid electrode of a MOStransistor Q5; and a flow valve driving circuit is used for carrying out primary-stage voltage regulation on a differential amplifier which takes an operational amplifier AR3 as the core, and the second-stage voltage regulation on the MOS transistor Q5 and then driving a flow valve motor, so that the output voltage of the drain electrode of the MOS transistor Q5 is stable, the adjusting precisionis improved, and the problem that the closed-loop feedback system is not timely adjusted is solved.

Description

technical field [0001] The invention relates to the technical field of aerodynamic vehicles, in particular to an engine power compensation system of an air vehicle. Background technique [0002] The full name of the air car is a compressed air-powered car. It uses high-pressure compressed air as the power source and air as the medium. During operation, it uses high-pressure compressed air to expand in the cylinder of the motor to do work, and pushes the piston to do work to output power to drive the car. It does not consume fuel. It is a real zero-emission environment-friendly car, which can effectively alleviate the serious air pollution in cities and the lack of oil resources. For this reason, many countries are actively investing in research on air-powered cars. [0003] The running performance (starting, braking, acceleration and deceleration performance) of the air car mainly depends on the accuracy and stability of the engine power of the air car, while the accuracy an...
