On-chip brain intelligent complex control system and construction and training method thereof

The invention discloses an on-chip brain intelligent complex control system which comprises an on-chip brain basic module and an on-chip brain information interaction and training module. The on-chip brain information interaction and training module comprises a neural signal decoding unit, a reward and punishment control unit, a task control model and a mapping relation model; the neural signal decoding unit is used for converting the neural response data into a control instruction which can be identified by external equipment; the task control model is used for a control task of the external equipment, the task control model generates a target control instruction of the next time according to the task feedback information, and the task control model can obtain a neural response corresponding to the target control instruction according to the corresponding relation; the mapping relation model is used for constructing a mapping relation between the on-chip brain stimulation sequence and the nerve response; and
