[0060] According to the environmental parameter data collected in real time, the environmental parameter estimation algorithm based on time series data prediction is used to process and analyze the environmental parameter data collected in real time, and the environmental parameter data at a certain moment in the future is predicted by combining the time decay mechanism with the weighted influence of the environmental parameter historical data, that is, the future environmental parameter prediction value;
[0061] The environmental parameter estimation algorithm based on time series data prediction reflects the change trend of the current environmental parameter data relative to the historical environmental parameter data by calculating the change rate of each environmental parameter, and helps predict the future change direction and rate of the environmental parameter data; based on the difference between the environmental parameter data at the current moment and the environmental parameter data at a certain moment in history, the change rate of the environmental parameter is obtained after normalization processing of the historical time interval; after the change rate of the environmental parameter is calculated, it is multiplied by the predicted time interval to calculate the preliminary adjustment of the future environmental state based on the current environmental parameter change trend, and the change range of the environmental parameter at the future moment is inferred by using the current environmental parameter data and the change rate of each environmental parameter;

[0076] The feedback correction process is realized by calculating the error between the preliminary control instruction and the actual response of the device. When the error is extremely large, the feedback correction value is also extremely large; when the error is extremely small, the feedback correction value is also extremely small. In order to avoid instability of the remote control system of the shrimp and crab three-dimensional breeding facility caused by over-adjustment, square and logarithmic adjustment are also combined to ensure that excessive reaction to the error can be suppressed, so that the remote control system of the shrimp and crab three-dimensional breeding facility can smoothly transition and avoid the occurrence of mutations or shocks.

It represents the logarithmic adjustment factor, which reduces the correction amplitude in the case of large errors by logarithmically transforming the square of the error term, thus avoiding overreaction of the remote control system of shrimp and crab three-dimensional breeding facilities in the case of large errors, smoothing the feedback correction, and enhancing the stability of the remote control system of shrimp and crab three-dimensional breeding facilities;
[0080] In order to avoid equipment damage or instability of the remote control system of shrimp and crab three-dimensional breeding facilities due to overcorrection, the saturation function is used to saturate the preliminary control instructions to ensure that the final control instructions will not exceed the operating limit of the equipment and prevent the equipment from overloading or overreacting;
