摘要： 对于一类工作点可变的单输入输出线性系统,被控系统表达为两个典型工作点上传递函数即正则稳定又既约分解的线性内插.文献[1,2]提出了一种固定型镇定控制器设计方法,文献[3]则提出了一种内插型镇定控制器设计方法,文中从理论上证明了文献[3]中提出的内插型镇定控制器能镇定更大范围的被控对象.

Abstract: For a linear SISO plant with variable operating condition, whose dynamics is described by a linear interpolation of proper stable coprime factorizations of the transfer functions at two representative operating points, a fixed stabilizer is proposed in[1,2]while an interpolated stabilizer is proposed in[3]. It is demonstrated in this paper that the class of stabilizable plants via the stabilizer proposed in[3]is larger than that via the fixed controllers proposed in[1,2].

Key words: fixed stabilizer, interpolated stabilizer, stabilizability, variable operating condition
