Abstract
A hybrid control system and a method for predicting a behavior of a physical system using the hybrid control system is disclosed. The hybrid control system may include a model inverting control system capable of implementing a model inverting control law and determining an active set of goals and limits and a model predictive control system capable of implementing a model predictive control law and utilizing the active set of goals and limits to determine current effector requests, the current effector requests being used to control behavior of the physical system.

A hybrid control system for predicting a behavior of a physical system, the hybrid control system comprising:
- a model inverting control system capable of implementing a model inverting control law and determining an active set of goals and limits;
- and
- a model predictive control system capable of implementing a model predictive control law and utilizing the active set of goals and limits to determine current effector requests, the current effector requests being used to control behavior of the physical system.
A method for predicting behavior of a physical system, the method comprising:
- providing a hybrid control system having (a) a model inverting control system capable of implementing a model inverting control law;
- and (b) a model predictive control system capable of implementing a model predictive control law;
- receiving one or more commands and limits as inputs;
- determining by the model inverting control system an active set of goals and limits based upon the one or more commands and limits;
- inputting the active set of goals and limits along with the one or more commands and limits into the model predictive control system;
- and
- computing current effector requests based upon the active set of goals and limits for controlling behavior of the physical system.
A hybrid control system, comprising:
- a model inverting control system capable of receiving one or more commands and limits and generating an active set of limits and goals;
- a model predictive control system capable of receiving the one or more commands and limits and the active set of goals and limits to generate current effector requests in a single iteration;
- an actuator servo loop capable of converting the current effector requests into actuator commands;
- one or more actuators capable of receiving the actuator commands and controlling a behavior of a physical system;
- and
- an estimator capable of providing feedback to the model predictive control system and the model inverting control system.
