The tracking problem is considered for robot manipulators. We propose a state feedback control algorithm which guarantees arbitrary attenuation on the outputs (the joint positions) of the effects of unknown timevarying disturbances as well as of parameter uncertainties.

โฆ Synopsis
In this paper we consider the benchmark nonlinear control problem and use backstepping to design several active controllers for tracking and disturbance attenuation; these two problems are much more challenging than stabilization. We show that the significant flexibility of backstepping can be exploited to reduce the required control effort and to eliminate the winding problem.

This paper deals with the problem of robust stabilization and disturbance attenuation via measured feedback, for a class of dissipative collocated distributed systems with disturbances affecting both the input and the measured output. The proposed solution is based on a direct L -gain characterizati
In this paper, we consider the problem of finite-time H -optimal control of linear, singularly perturbed, discrete-time systems. The problem is addressed from the game theoretic approach. This leads to a singularly perturbed, matrix Riccati difference equation, the solution of which is given in term
