What is the bandwidth of the control system?What parameters determine the bandwidth?

The concept of bandwidth: Bandwidth refers to the amount of data that a communication channel (such as a network, cable, optical fiber, etc.) can transmit in a unit of time. It is usually expressed by bit rate (bit/s) or byte rate (Byte/s).

In the process of using broadband, the three parameters involved are usually the material of broadband, the bandwidth of broadband, and the transmission speed of broadband.

Network bandwidth is determined by the following aspects: the type and performance of network transmission media: network transmission media include wired, wireless, optical fiber, etc. Different media have different bandwidth and transmission rates.

stripe size is the total amount of data continuously written on each disk, also known as "strip depth".You can specify the strip capacity of each logical drive from 2KB, 4KB, 8KB to 128KB. In order to obtain higher performance, the capacity of the stripe should be equal to or less than the size of the cluster of the operating system.

. Limit the maximum bandwidth that 1916100 can use at 600Kbps; the five IP addresses of 1916101-1916105 share bandwidth, and limit the maximum sum of the bandwidth they can use to 1500Kbps.

What are the main parameters of each power component of a pure electric vehicle, and how are they determined during design?

The technical parameters of pure electric vehicles mainly include the following aspects: Battery capacity: Battery capacity refers to the amount of electricity that the battery can store, generally expressed in kilowatt-hours (kWh). Range: Range refers to the maximum mileage that an electric vehicle can travel on a single charge, which is generally expressed in kilometers.

New energy vehicles include pure electric vehicles (BEV, including solar vehicles) and hybrid electric vehicles (HEV), fuel cell electric vehicles (FCEV), other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage devices) vehicles, etc. Since the emergence of new energy vehicles, there are mainly three types of power: hybrid power, pure electric power and fuel cell.

The motor drive control system is the main executive structure in the operation of new energy vehicles. The drive motor and its control system are one of the core components (batteries, motors, electronic control) of new energy vehicles. Its driving characteristics determine the main performance indicators of automobile driving. It is an important component of electric vehicles.

The maximum working speed is the maximum speed that the motor can reach at rated voltage, which affects the maximum design speed of pure electric vehicles. 5. Rated torque Rated torque refers to the output torque of the motor under the rated power and rated speed.

What are the control parameters in the automatic control system?

Automatic control refers to the use of additional equipment or devices to automatically run a working state or parameter of the machine, equipment or production process according to the predetermined law when no one is directly involved. Automatic control is relative to the concept of manual control.

The parameters in the process control system are also called parameters and variables. Controlled parameters (parameters, variables) refer to the target object of control, that is, the purpose and object of control, which are generally reflected in the numerical value required by the parameter (the control value required by the process). It is also known as the modulation parameter.

The automatic control system can be divided into open-loop control system and closed-loop control system.A control system includes controller, sensor, transmitter, actuator, input and output ports.

What are the distribution parameters of the distribution parameter control system?

1. The controlled object or controller needs to be described by distribution parameters. The control system is called the distribution parameter control system. In addition to the controlled object in engineering technology, the control device or actuator may also be a distributed parameter system.

2. The distribution of parameters means that the potentials and currents of two adjacent points in the circuit are different at the same moment. This shows that the voltage and current in the distributed parameter circuit are not only functions of time, but also functions of spatial coordinates.

3. Whether the circuit is a distributed parameter circuit depends on the relationship between the maximum line size of the circuit itself and the current or voltage wavelength λ in the circuit. When λ, the circuit can be regarded as a total parameter circuit; otherwise, it should be regarded as a distributed parameter circuit.
