“…In terms of linear systems, this problem has been well solved for some different types of systems. For example, see [63,64,[72][73][74][76][77][78][79], etc. Compared with linear stochastic systems, the research on controllability of nonlinear stochastic systems has made slow progress, but many research results have also been achieved (e.g., [80][81][82][83][84][85][86][87]).…”
