Tracking Control of Linear Systems

Chapter 12 Natural Tracking Control (NTC)

12.1 Concept of NTC

What does the nature, i.e., the brain as the part of the nature, use to create control of any organ? It uses evidently information about the error ɛ of the real organ behavior Y (.) relative to its desired behavior Y_d (.). But, this is not the only information that the brain uses to create the control. For example, in order to control the position of a hand, of a finger, of a leg, the brain uses information about the difference between their desired and real positions, which is information about their position errors. However, the brain simultaneously uses information about the forces of the muscles acting on the organs. The muscle force is a control variable. The brain, as the central ...
