This invention relates to the interdisciplinary field of agricultural machinery automation control and precision spraying / fertilizer equipment. More specifically, it relates to a physical control method for variable-operation agricultural and forestry operations based on optical impedance dissipation. Addressing the problem of mis-spraying due to blurred boundaries in variable-operation agricultural machinery, this invention utilizes onboard multi-channel optical hardware to acquire radiation field data. A fractional-order optical attenuation background tensor and a joint impedance tensor are constructed to define the physical barrier boundaries of micro-operations in agricultural machinery. Under this constraint, the minimum dissipation optical path is calculated and the mesoscopic state field is reconstructed, revealing the physiological stress gradient mapped to the hydraulic response. This gradient is then converted into an onboard prescription map, and a PWM control signal with a duty cycle accuracy ≥0.1% and a delay ≤10ms is output via a CAN bus to drive the electro-hydraulic proportional valve of the agricultural and forestry equipment. This invention achieves a millisecond-level physical closed loop from optical sensing to hydraulic execution, preventing mis-spraying at the hardware and electrical level and completing targeted physical control.
