The chaotic dynamics of Belousov-Zhabotinsky chemical reaction in continuous flow stirred tank reactor (CSTR) is controlled by two methods: (1)a self-adaptive delay feedback control scheme; (2)a linear self-interacting control method. The first control method is a kind of perturbation control and can stabilize the BZ-CSTR chemical chaos to its embedded unstable periodic orbits (UPO). The advantage of the method is illustrated by the self-adaptive regulation of the system delay time. The second control method can drive the BZ-CSTR chaotic dynamics to a new status of dynamics which may not be the original embedded intrinsic orbits of the chaos. Both methods illustrate great flexibility and effectiveness in controlling BZ-CSTR chemical chaos.
