Problems solved by technology

[0004] However, communication methods such as Ethernet transmit discrete data, and the amount of data is small, so the commands output from the PLC to the motor driver are not continuous, and the output of the motor driven by the motor driver may jump

Abstract

The embodiment of the invention discloses a load simulation method, device and system and a process controller. The method comprises the following steps: receiving M load data points from an upper computer; determining an interpolation function based on the M load data points; sampling N load data points from the interpolation function; generating a driver control instruction based on the N load data points, wherein N is greater than M, and M and N are both positive integers. According to the embodiment of the invention, the load data volume is increased through interpolation processing, the driver control instruction generated based on the load data is more continuous, the output of the motor connected with the driver is smoother, and the jump problem of the motor output is effectively relieved.

Description

technical field [0001] The invention relates to the technical field of simulation, in particular to a load simulation method, device, system and process controller. Background technique [0002] Simulation generally refers to the establishment of a model for a real or abstract system, transaction or process based on experiments or training to characterize its key characteristics or behaviors and functions, and to systematize and formulate it so that it can be Simulate key features. The load simulation system can simulate the respective load parameters in the actual system, such as simulating load force or simulating load torque through the output of the motor. [0003] The current load simulation system mainly includes computer, programmable logic controller (PLC), motor driver and motor. The load curve is planned on the computer, and the data on the load curve is transmitted to the PLC through communication methods such as Ethernet (Ethernet). Then, the PLC converts the ...
