3.6.2.1 Comparison of Proposed Algorithm with Conventional Sliding Mode Control

In this section, the experimental results of proposed algorithm are compared with conventional sliding mode control. The results of tracking response, control signal and sliding variable for total networked delay of are shown in Fig. 3.11a–f. From the comparative results, it can be noticed that the conventional sliding mode control becomes unstable for a small delay of . Thus, the Thiran approximation proved to be an efficient method in discrete-time sliding mode control. Simulation and experimental results for different networked delays range are summarized in Table 3.1. The comparison of discrete-time sliding mode control with time delay approximation and conventional sliding mode control is shown in Table 3.2.
