in this article, the sliding mode control of frequency load control of power systems is studied. the study areaconsists of a system of water and heat. first, a mathematical model of the proposed system disturbances ismade and then sliding control mode for frequency load control is provided. by the system simulation andsliding mode control, it can be shown that the damping of oscillations is wel...

The role of nucleus tractus solitarius (NTS) in cardiovascular system regulation is controversial. On the other hand, the problem of hypertension in diabetic animals is the subject of many research programs. The aim of present study was to determine whether inactivation of NTS could affect blood pressure and heart rate in diabetic rats. To this end, stereptozotocin induced diabetic rats were an...

During the coking process in coal chemical industry, the stability of gas collector pressure is an important guarantee for the normal production of coke oven. This paper combines the adaptive fuzzy control algorithm and the fuzzy decoupling rule to control the gas collector pressure, and coordinates the entire system through the establishment of pre-header suction supervisory control. The speci...

background: today, endoscopic evaluation of digestive system is an important diagnostic approach in gastrointestinal diseases. as it is an invasive method, it causes fear and anxiety in patients. the current study was fulfilled to evaluate the effect of music therapy during endoscopy on the anxiety of patients by measuring blood pressure. methods: this is an experimental study of single blind c...
