摘要：

A novel control scheme is proposed to solve the problem of stabilizing nonlinear uncertain systems with unknown sign of the control gain and potentially unbounded nonlinearities. If the drift term f (x) has a growth rate such that the overall system has a finite escape time t*, only a guess of a lower bound, different from zero, of t* is necessary to design the control law. The properties of the proposed algorithm are compared with those of a well-known adaptive control procedure when applied to the same class of systems. Copyright (C) 2001 IFAC.
