An alternative is to compute the peak-to-peak value ypp. As a result, small changes in the air pressure applied to the valve do not change the flow rate.

Came into use in s with the introduction of pneumatic controllers. Extremely flexible and powerful control algorithm when applied properly. Closed Loop Transfer Functions From the general feedback control loop and using the properties of transfer functions, the following expressions can be derived:. Characteristic Equation Since setpoint tracking and disturbance rejection have the same denominator for their closed loop transfer functions, this indicates that both setpoint tracking and disturbance rejection have the same general dynamic behavior. The roots of the denominator determine the dynamic characteristics of the closed loop process. The characteristic equation is given by:. As Kc is increased from zero, the values of the poles begin to approach one another.

This technical note presents a possible current control implementation for power converters. First, the note introduces the general operating principles of a simple Proportional-Integral PI controller. Then, an example of current control for a boost converter is provided. PI controllers are widely used in power electronics, thanks to their simple structure and implementation. They are very frequently used to control constant or slowly-varying quantities, e. When implemented in a parallel form, a PI controller can be represented as shown below:. The simplest and most obvious example of PI-based control is certainly given by the control of the inductor current within a boost-type converter. A widely-accepted model for the proposed system is shown below. Four distinct parts can be clearly identified. The sampling corresponds to a zero-order hold ZOH which introduces a lag, which is the sampling delay.

There are different ways to determine T. Transl 2 1 , 95— 8. To avoid making the system sensitive to measurement noise, the loop gain should not be made too large. This stabilization problem is solved in this chapter. In this work, the RLS algorithm was extended to also cater for self-tuning of the controller. The gain can be obtained as the slope of the curve in Figure 2. On the other hand, they are more sensitive to low-frequency disturbances such as a change in static load. The lin- ear range can be specified either by giving the slope of the character- istic controller gain K or by giving the range where the character- istic is linear proportional band Pb. The initial value of matrix P is typically chosen as the identity matrix multiplied by a large number. An inherent property of disturbances is that they cannot be predicted exactly. In this diagram the process and the controller are repre- sented as boxes with arrows denoting inputs and outputs. Assume that the system is in steady state with a constant control signal u0 and a constant error e0. Dis- turbances is another important side of the control problem. We have not attempted to be complete in citing this literature.

Example 9. Asian J. These regions overlap, but are not the same. Let h t be an impulse response and G s the corresponding transfer function. This represen- tation is obtained naturally when a controller is implemented as an analog device based on a pneumatic force balance system. Culture Documents. Typical values of N are 8 to Calculate the characteristic equation derived from Fig. However, this approach has several disadvantages: a it leads to conservative bounds; b it imposes limitations on the controller performance; c it does not prevent windup caused by disturbances.
