Description

technical field [0001] The invention relates to automatic control technology, in particular to a configurable mixed signal control system and method. Background technique [0002] Controllers are required in automation control. The controllers used today are usually implemented based on embedded digital microprocessors. Although microprocessors are powerful devices that have been widely used in various applications, there are many disadvantages in the implementation of microprocessor-based controllers in automation control. [0003] One disadvantage of using a microprocessor to implement a controller arises from the serial operation mechanism of the microprocessor. Microprocessor-based controllers work by scanning input / output ports and then executing instructions. Therefore, the response of the controller is very dependent on the speed of the embedded microprocessor and the number of input / output ports. The more input / output ports a microprocessor in a controller has to...

Problems solved by technology

Although, in the configurable controller, the programmable analog module can perform some specific functions, but the programmable analog module performs very limited auxiliary functions, and the main function of the controller is still performed by the microprocessor

[0006] It can be seen from the above description that in the prior art, the main functions of the controller must be realized based on the embedded microprocessor. Therefore, limited by the working mechanism of the microprocessor, in the application of automatic control, the controller cannot Provides input / output scalability while meeting speed requirements, furthermore, due to the use of analog / digital converters, problems such as quantization errors, aliasing, and high power consumption will greatly reduce the performance of the controller
