“…Recently, a novel mathematic method called the semi-tensor product (STP) was proposed by Cheng et al (2011), by which logical dynamics can be converted into linear representation and further analytical analysis can be implemented. Consequently, some impressive results have been achieved, especially for the in-depth research on control-related problems, such as controllability (Cheng and Qi, 2009;Li and Sun, 2011a;Laschov and Margaliot, 2012), observability (Cheng and Qi, 2009;Li et al, 2011), realization (Cheng et al, 2010), stability (Li and Sun, 2011b) and control for disturbance decoupling , etc. Wherein, controllability is a fundamental problem in control field.…”
