Techniques for controlling a bottom hole assembly, BHA (118) include determining a model of BHA dynamics based on sensor measurements (320) from the BHA (118); determining, based on the model of BHA dynamics, an objective function including a predicted future deviation from a planned wellbore path; determining a control input (310) to the BHA (118) that satisfies the objective function for a set of operating conditions of the BHA (118); generating, at a secondary system, relational information that relates the control input (310) to the set of operating conditions; and transmitting the relational information from the secondary system to the BHA (118). The most suitable drawing: FIG. 1.
