H. Koroglu et O. Morgul, Time-varying repetitive control for better transient response and stochastic behaviour, ELECTR LETT, 37(17), 2001, pp. 1101-1102
A stability proof is given for a time-varying repetitive control strategy.
It is illustrated by a simulation example that this time varying strategy c
an be used to improve the transient reponse and stochastic behaviour of the
repetitive control system simultaneously.
