代写termpaper-Chapter 1 automatic control, the general concepts
1.1 automatic control of the basic principle and method
1.2 the classification of automatic control system
1.3 to the automatic control system of basic requirements
1 what is the automatic control: the so-called automatic control, it is to point to in no one directly involved in conditions, the additional equipment or device (controller), to make the machine, equipment or production process (the controlled object) a condition or parameters (the controlled variables) automatically set to run law.
2 the automatic control system is to point to by control device and controlled object of combined, can be controlled object of some parameters for automatic control of an organic whole
3 the controlled object: requests to realize the automatic control equipment, the production process, or other objects
4 be control quantity: refers to the control system to control the physical quantities, generally refers to the system output
5 control quantity: can be changed, and influenced by the amount of physical quantity control, generally refers to the system input amount
6 disturbance: damage control quantity and be controlled normal function relation between the factors, known as a system disturbance
7 control device: can be controlled object to the control effect of the equipment floorboard 【 controller, control valves 】
8 detection device: some physical measurement system of the value of the temperature sensor 】 device
Hot water system charts
9 for the control system of the basic requirements
Basic requirements: stability and speed, accuracy (steady, fast, accurate), anti-jamming
(1) stability: the stability control system, which is accused of quantity of the expected value deviation from the initial error should be changes with time to zero
Constant value system: is accused of recovery of value
Servo system: was charged to the new value of tracking
(2) efficiency: refers to the process of transition form and fast full, called dynamic performance
(3) accuracy: refers to the process of transition after the end of the steady-state error smaller may be more beautiful
Steady-state error: refers to the transition process ended, hope output and the actual the error between the output
The typical 1.3.2 role
Several typical input: step function, slope function, acceleration function pulse function, sine function
Laplace transform
