这份报告涉及到离散时间系统，它是由脉宽调制(PWM)保持得到的连续时间LTI系统得到的。描述离散系统的差分方程的输入项是PWM信号控制参数的非线性映射，即占空比。结果表明，对于二维系统，通过改变每个矩形脉冲波形的中心及其占空比，可以精确地补偿PWM保持系统的非线性。
This report is concerned with discrete-time systems that are derived for continuous-time LTI systems by the pulse-width-modulation (PWM) -hold. The input term of the difference equation describing the discrete-time system is a nonlinear map of the control parameter of the PWM signal, i.e., duty ratio. It is shown that for two-dimensional systems, the nonlinearity of the PWM-hold systems can be exactly compensated by varying the center of each rectangular pulse-waves as well as its duty ratio.
