Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The valve opening control method provided by the application can be applied to the application environment shown in fig. 1. Wherein the bypass valve controller 102 communicates with the server 104 over a network. The server 104 obtains an actual opening degree of the bypass valve recorded in the bypass valve controller 102, if the actual opening degree is different from a target opening degree, the speeds corresponding to the bypass valve in different working processes are obtained, a difference value between the speeds and the target speed is further calculated, and if the difference value is not equal to zero, the H-bridge voltage is adjusted through a PI algorithm so that the actual opening degree is the same as the target opening degree. The server 104 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2 and 3, a valve opening control is provided, which is illustrated by applying the method to the server 104 in fig. 1, and includes the following steps:
step S1: acquiring the actual opening degree of the air bypass valve;
step S2: if the actual opening degree is different from the target opening degree, acquiring speeds corresponding to the bypass valve in different working processes;
step S3: and calculating the difference value between the speed and the target speed, and if the difference value is not equal to zero, regulating the voltage of the H bridge through a PI algorithm to enable the actual opening degree to be the same as the target opening degree.
In steps S1 to S3, the target opening and the target speed are set inside the server 104, and may be adjusted according to circumstances, and are not particularly limited. The operating state of the bypass valve includes at least an open state and a closed state. The adjustment direction of the bypass valve is opposite between the open state and the closed state, for example, the adjustment direction of the bypass valve in the open state is counterclockwise, and the adjustment direction of the bypass valve in the closed state is clockwise. When the air pressure changes, the direct PI adjusting valve actual opening is changed into the opening/closing speed of the PI adjusting valve, so that the calibration parameters can be reduced, the algorithm robustness is enhanced, the overshoot and the oscillation in the closed-loop adjusting process can be obviously reduced, and the influence of opening adjustment on the stability of an air system is reduced.
The valve opening control method comprises the following steps: and if the difference value is not equal to zero, adjusting the voltage of an H bridge through a PI algorithm to enable the actual opening degree to be the same as the target opening degree. The method can obviously reduce the overshoot and the oscillation in the closed-loop regulation process and reduce the influence of the opening regulation on the stability of the air system.
In one embodiment, the step S2 includes:
step S21: if the actual opening degree is different from the target opening degree, acquiring a first opening degree corresponding to a first period of the bypass valve and a second opening degree corresponding to a second period of the bypass valve;
step S22: determining the opening speed of the bypass valve according to the first opening degree and the second opening degree;
step S23: if the actual closing opening degree is different from the target closing opening degree, acquiring a first closing opening degree corresponding to a first period of the bypass valve and a second closing opening degree corresponding to a second period of the bypass valve;
step S24: and determining the closing speed of the bypass valve according to the first closing opening degree and the second closing opening degree, wherein the first period and the second period are two continuous periods with the same time.
In steps S21-S24, a target opening degree is set inside the server 104 when the bypass valve is in the on state, and the target opening degree is adjusted according to specific conditions, without limitation. If the actual opening degree of the bypass valve is different from the set target opening degree, the opening degrees of the bypass valve in two continuous periods (a first period and a second period) are collected, and then the opening speed is determined according to the first period and the second period, wherein the first period and the second period are sampling periods, such as 5ms and 10ms, and the like, and are not limited specifically. The process of the bypass valve being in the closed state is analogized.
In one embodiment, the step S22 includes:
step S221: calculating the difference value of the first opening degree and the second opening degree to obtain an opening degree difference value;
step S222: and determining the opening speed of the bypass valve according to the opening difference and the time corresponding to the first period, or according to the opening difference and the time corresponding to the second period.
In steps S221 to S222, if the first opening degree is 40 and the second opening degree is 50, the opening degree difference is 10. Further, since the time corresponding to the first period and the second period is the same and may be set to 10ms, the opening speed of the bypass valve may be determined by opening the opening difference 10 for 10ms corresponding to the first period, or opening the opening difference 10 for 10ms corresponding to the second period. I.e. VIs openedEqual to the opening difference 10 divided by the time 10 ms.
In one embodiment, the step S24 includes:
step S241: calculating the difference value of the first closing opening degree and the second closing opening degree to obtain a closing opening degree difference value;
step S242: and determining the closing speed of the bypass valve according to the closing opening difference value and the time corresponding to the first period, or according to the closing opening difference value and the time corresponding to the second period.
In steps S241 to S242, if the first closing opening degree is 40 and the second closing opening degree is 50, the closing opening degree difference is 10. Further, since the time corresponding to the first period and the second period is the same and may be set to 10ms, the closing speed of the bypass valve may be determined by closing the opening difference 10 for 10ms corresponding to the first period, or closing the opening difference 10 for 10ms corresponding to the second period. I.e. VClose offEqual to the closing opening difference 10 divided by the time 10 ms.
In one embodiment, the step S3 includes:
step S31: acquiring a target opening speed;
step S32: calculating the difference value between the opening speed and the target opening speed to obtain the opening speed difference value;
step S33: and if the opening speed difference is not equal to zero, adjusting the voltage of the H bridge through a PI algorithm to enable the actual opening degree to be the same as the target opening degree.
In steps S31-S33, the target opening speed is set inside the server 104 and adjusted according to different situations, and is not particularly limited. If the opening speed is different from the target opening speed, the H-bridge voltage needs to be adjusted by adopting a PI algorithm so that the actual opening degree is the same as the target opening degree.
In one embodiment, the step S3 further includes:
step S34: acquiring a target closing speed;
step S35: calculating the difference value between the closing speed and the target closing speed to obtain a closing speed difference value;
step S36: and if the closing speed difference is not equal to zero, adjusting the voltage of the H bridge through a PI algorithm to enable the actual closing opening degree to be the same as the target closing opening degree.
In steps S34-S36, the target closing speed is set inside the server 104 and adjusted according to different situations, and is not particularly limited. If the closing speed is the same as the target closing speed, the actual closing opening degree is the same as the target closing opening degree, and if the closing opening degree is not the same as the target closing speed, the H-bridge voltage needs to be adjusted by adopting a PI algorithm so that the actual closing opening degree is the same as the target closing opening degree.
In one embodiment, the method further comprises:
step S4: and if the actual opening degree is the same as the target opening degree, acquiring the H-bridge voltage corresponding to the actual opening degree of the bypass valve, and keeping the H-bridge voltage constant.
Specifically, when the actual opening degree is the same as the target opening degree, an H-bridge voltage corresponding to the actual opening degree needs to be collected, for example, the H-bridge voltage is 10V, the H-bridge voltage is maintained at 10V, and the opening degree of the bypass valve does not change any more.
