Abstract
Concerns the design of intelligent controllers for a class of
exercise machines. The control objective is to cause the user to
exercise in a manner which optimizes a criterion related to the user's
mechanical power. The optimal exercise strategy is determined by a
biomechanical behavior of the individual user, which is assumed to
satisfy an affine force-velocity relationship dependent on the body
geometric configuration. Consequently, the control scheme must
simultaneously: 1) identify the user's biomechanical behavior; 2)
optimize the controller; and 3) stabilize the system to the estimated
optimal states. Moreover, to ensure that the exercise machine is safe to
operate, the control system guarantees that the interaction between the
exercise machine and the user is passive. We formulate the control
problem and propose a controller structure which satisfies the safety
requirement and is capable of causing the user to execute an arbitrary
exercise strategy if the user's biomechanical behavior is known. The
controller is of the form of a dynamic damper and can be implemented
using only passive mechanical components
