A study on control of novel corona-virus (2019- nCoV) disease process by using PID controller

Abstract

Background, In this paper, the SEIR dynamic model will be used to model the epidemic of coronvirus (2019-nCoV)disease. The SEIR model has been used to model infectious diseases in Malaysia.Then, the spread and control of the disease is simulated applying a PID controller. The results of this study show that the implementation of strict restrictions such as quarantine, social distancing and closure of gathering centers is effective in controlling the disease. Using the results and analyzing them, it was found that early and strict implementation of strict restrictions such as quarantine, social distance and closure of centers with a high percentage of community is very important to control this disease and prevent irreparable economic losses and depreciation of medical staff.Objective: Modeling the prevalence and control of corona-virus (2019-nCoV)and the impact of government actions using control engineering methods. Method:In this study, the SEIR dynamic model was used and the common data on the prevalence of the virus in Wuhan, China and Malaysia were used. As an example, the use of control target schemes is simulated in this paper. Results:The findings of this study use control methods and forecasting in control engineering to provide a clear picture of macro-decisions for different governments in the field of infectious diseases. Conclusion:Management and control schemes such as travel restrictions, quarantine, social distance and closure of offices, higher education institutions must be implemented immediately to prevent major economic and social losses. The implementation of these restrictions should not be delayed during the outbreak of corona-virus(2019-nCoV) infectious diseases.

Physical Distancing Alarm System Based on Proximity Sensor and Microcontroller

“…The transmitter will emit high-frequency sound waves that travel at a speed of around 340 m / s. When the wave hits an object, the waves will be reflected and received by the receiver. The distance between the sensor and the object is calculated according to the required time of wave to travel between the transmission and received by the receiver as shown in Equation (1).…”

“…The Coronavirus outbreak that began to spread in late 2019 in Wuhan, China, has changed people's perception around the world about health, social interactions, etc [1][2][3][4][5]. The pattern and speed of spread, the effects, and virus's ability to mutate are some of the considerations that cause a high level of vigilance in the face of the spread of this virus [1,4].…”

As the global health authority, World Health Organization (WHO) has announced the status of a pandemic against this type of virus, including the various efforts for dealing with the situation amid this pandemic [1,4]. To reduce the spread of Coronavirus Diseases (Covid-19), the health protocols such as using masks, diligently washing hands, maintaining distance, avoiding crowds, and reduce mobility must be implemented [6][7][8][9].…”

“…Therefore, the availability of automatic alarms for measures the safety distance can facilitate the humans for interaction, especially in public facilities, and prevent Coronavirus transmission. Various systems could be utilized to develop distance detection systems such as GPS, artificial intelligence, sensor systems, and others [1,3,5,[11][12][13]. However, the growth of instrumentation, automation, and sensor systems have enabled the development of accurate, user-friendly, and low-cost automatic alarm systems.…”
