On the other hand, in sampled-data systems some signals are continuous and others are discrete in time. Some of the discrete-time signals come from continuous signals through sampling. An example of a sampled-data system is the control of a continuous process by a digital computer. The digital computer only accepts signals at discrete points of time so that a sampler must transform the continuous time signal to a discrete time signal.

Now we can give the definition of sampled-data systems. Sampled-data systems are systems that process sampled-data signals or discrete signals. Furthermore, nonlinear sampled-data systems are sampled-data systems that additionally possess

Sampled-data system is a kind of hybrid system that contains both continuous and discrete signals (Chen & Bruce, 1995). Compared with other continuous-time control systems, the sampled-data system has the characteristics such as wide application, simplicity and effectiveness. With the rapid development of digital controllers, the sampled-data control system has attracted extensive attention in recent years (Li & Shen, 2020; Liu & Huang, 2019; Zeng et al., 2017, 2019; Zhang et al., 2016; Zhao et al., 2016). Stability is one of the fundamental issues for sampled-data systems, and to increase the sampling interval is helpful for reducing the calculation burden and data transmission rate (Shao et al., 2017). Therefore, the study on stability has important theoretical value and engineering significance.
