| 摘 要： | The chaotic behaviours in the p--Ge photoconductor system
are studied by changing the photo-excitation coefficient and the
routes and parameter conditions are given for chaos generation in
this system. A scheme for controlling chaos in the p--Ge
photoconductor is presented by adding an ac bias current. Numerical
simulations show that this scheme can be effectively used to control
chaotic states into stable period states for this system. Moreover,
the different period states with different period numbers can be
obtained by appropriately adjusting the amplitude, frequency, and
initial phase of the additional ac current.
