Abstract :
The author presents ´proportional+integral (P+I) adaptive laws for combined adaptive control, using closed-loop estimation errors. The global uniform stability of the overall system is shown by constructing a new Lyapunov function. Simulation results show that the ´P+I´ form laws yield improved performance.
