A Modification of PI Controller Based on an Online Adaptive Approach to Use in Networked Control Systems for Remote Surgery

Conclusion: The proposed system performs better than the traditional approach in terms of measuring the average value of the error, recall, and ITAE. According to simulation and practical results, when the network average time delay is about 40ms, the performance index for an online adaptive PI controller is equal to 4.4236, and value for a classic PI controller is 4409. Thus, the performance of an online adaptive PI controller has been improved about 1000 times rather than a classic one. Therefore, the proposed controller in real network time delay has proper performance and keeps the stability of the control loop.
