[amp_mcq option1=”Servo signal” option2=”Desired variable value” option3=”Error signal” option4=”Sensed signal” correct=”option3″]<\/p>\n
The correct answer is: C. Error signal<\/strong><\/p>\n An error signal is the difference between the desired value of a variable and the actual value of the variable. It is the input to a controller, which uses the error signal to calculate an output signal that will reduce the error.<\/p>\n A servo signal is a type of control signal that is used to control the position, velocity, or acceleration of a mechanical system. It is typically generated by a controller and sent to a servo motor, which then uses the signal to move the system in the desired way.<\/p>\n A desired variable value is the value that a controller is trying to achieve for a particular variable. For example, if the controller is trying to control the temperature of a room, the desired variable value would be the desired temperature of the room.<\/p>\n A sensed signal is a signal that is generated by a sensor and represents the value of a physical quantity. For example, a temperature sensor might generate a signal that represents the temperature of the environment.<\/p>\n In conclusion, the error signal is the input to a controller. It is the difference between the desired value of a variable and the actual value of the variable. The controller uses the error signal to calculate an output signal that will reduce the error.<\/p>\n","protected":false},"excerpt":{"rendered":" [amp_mcq option1=”Servo signal” option2=”Desired variable value” option3=”Error signal” option4=”Sensed signal” correct=”option3″]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[961],"tags":[],"class_list":["post-50357","post","type-post","status-publish","format-standard","hentry","category-electrical-control-systems","no-featured-image-padding"],"yoast_head":"\n
