Computer simulation is the use of a computer-generated system to represent the dynamic blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions of a real or proposed system. A mathematical description of a system is developed as a computer program that uses equations to represent the functional relationships within blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions. When the program is run, the resulting mathematical dynamics form an analog, usually represented graphically, of the behaviour of the modeled system. Variables in the program can be adjusted to simulate blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions in the system. Computer simulations are used to study the behaviour of objects or systems that cannot be easily or safely tested in real life, such as weather patterns or a nuclear blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions. Simpler simulations performed by personal computers are business models and geometric blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions.
Servomechanism is a device used to correct the performance of a mechanism automatically, blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions of error-sensing feedback. The term properly applies only to systems in which the feedback and error-correction signals blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions mechanical position or velocity. Servomechanisms were first blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions in military and marine navigation equipment. Today they are used in automatic machine tools, satellite-tracking antennas, celestial-tracking systems on telescopes, automatic navigation systems, and antiaircraft-gun blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions systems. The design of servomechanisms is considered to be a branch of both robotics and blastby meanscontrolcyberneticsmodelsresponses and behaviourthe systemusedvarying conditions.
