Technical Field

Background
PID algorithms are widely used in industrial control and automation systems, for example, in temperature control, speed control and level control. In the temperature control method, a PID algorithm is generally used, and the formula is:
wherein u (t) is the output percentage, k p 、k i And k d E (t) is the error between the temperature at the time t and the set temperature,for the error integration at time t, +.>Is the differential of the error at time t.
As shown in fig. 1, after the PID algorithm outputs the percentage u (t), u (t) is input into the actuator, and the actuator adjusts the temperature according to the control object of u (t) to complete temperature control.
But in the process that the existing temperature control system realizes temperature control through a PID algorithm, the temperature control system feeds back the execution result u (t-1) of the previous PID temperature control algorithm to the PID temperature control algorithm again through an environment variable, namely e (t) =u (t-1) -a, wherein a is a set temperature, and the last result of repeated execution of the previous time is fed back to the next time for parameter input until the system tends to be stable. Because the PID algorithm needs to carry out integration and differential operation and repeatedly executes the feedback of the last result to the next parameter input, the MCU and the programming capability in the system are required to be higher; meanwhile, an executing mechanism in the system is adjusted in real time along with the temperature before the PID algorithm is stabilized, so that the power consumption is high, and the use of low-power consumption products is inconvenient.

After determining the motor stroke percentage, in order to make the effective control motor frequently used, a preset output period is set to control the motor stroke percentage to perform periodic output, so that the radiator can perform periodic temperature control according to the motor stroke percentage, for example:
when the motor stroke percentage of the radiator is determined to be 50%, calculating the time of the primary motor stroke percentage to be 1min, and setting a preset output period to be 5min; in the prior art, the motor stroke percentage is calculated once to output the motor stroke percentage once, and the temperature is controlled through the motor stroke percentage, namely, the motor stroke percentage is executed once per minute, so that the power consumption is high. In the embodiment of the application, the motor stroke percentages are periodically output according to the preset output period, namely, the motor stroke percentages of the first minute, the second minute, the third minute, the fourth minute and the fifth minute are calculated, then the motor stroke percentages of the four preceding minutes are not output, and only the motor stroke percentages of the fifth minute are output; similarly, no output was made for the sixth, seventh, eighth, and ninth minutes, with the tenth minute being output as a percent of motor travel.
