“…Extensions of the definitions of structural properties had been already introduced and thoroughly studied in the early 1970s [4]. During the 1980s, several works have dealt, instead, with the problem of controlling bilinear systems by means of different approaches, e.g., sliding-mode control [8], quadratic feedback [9], linear state feedback [10], and model reference control [6]. In the subsequent decades, more involved approaches have been devised, e.g., the qualitative analysis and stabilization method by Khapalov and Mohler [11,12] and also optimal control techniques [13,14].…”
