We present a model of the Belousov‐Zhabotinsky reaction with external controls. The Oregonator model is modified to include three different control parameters, i.e., flow rate, light intensity, and electric current. Applying cathodic or anodic current shifts bifurcation points in an opposite direction in a two‐parameter space spanned by light intensity and flow rate. This external control enables steady states to be sensitive to noise in the two‐parameter space. The use of shifting bifurcation points is discussed in relation with stochastic resonance.
