Design of Intelligent PID Controller for Smart Toilet of CCU/ICU Patients in Healthcare Systems

The necessity of a healthy environment is a major aspect in this modern age. Several trials have been made by multidisciplinary researchers for the development of a healthy environment. However, it is important to facilitate most of the modern healthcare resources to the unhealthy people for their betterment. Some extent of technology has an important role to support it. In this paper, a case study of water supply in healthcare system is analyzed. The paper has three aspects; first, the use of PI control for measuring the water level in a tank, second, the water distribution to several resources using PD control. The use of both the controls is further explained through an example of water distribution in a smart toilet. Lastly, the tuning of the PID controller using a fuzzy-based controller which makes the overall system robust. The simulation results confirm the advantages and demonstrate better dynamic behavior. For low energy consumption, either the input energy is decreased or the efficiency of mechanical transmission is increased. Performance of the controller is judged upon the simulation results obtained from MATLAB.
