Im trying to implement a direct inverse neurocontrol scheme, and I’m at a dead end. The error lies in the fact that after modeling, there is a large static error in the neurocontrol circuit, as if the regulator is not correctly producing a control signal. So, in simulink I built a diagram of the direct dynamics of a nonlinear system described by the following equation:
y′′+0.7y '+0.2y+0.3y^3−u=0
I also implemented a circuit that simulates the inverse dynamics of the system.
