Angle notation can easily describe leading and lagging current: . [1] In this equation, the value of theta is the important factor for leading and lagging current. As mentioned in the introduction above, leading or lagging current represents a time shift between the current and voltage sine curves, which is represented by the angle by which the curve is ahead or behind of where it would be ...
For example, economists have found that in some circumstances there is a lead-lag effect between large-capitalization and small-capitalization stock-portfolio prices. [2] (A loosely related concept is that of lead-lag compensators in control theory, but this is not generally referred to specifically as a "lead-lag effect.") [citation needed]
Lead–lag compensation places both a zero and a pole in the open loop response, with the pole usually being at an open loop gain of less than one. Feed-forward or Miller compensation uses a capacitor to bypass a stage in the amplifier at high frequencies, thereby eliminating the pole that stage creates.
In international finance, leads and lags refer to the expediting or delaying, respectively, of settlement of payments or receipts in a foreign exchange transaction because of an expected change in exchange rates.
Usually, it is done by conditioning the input or the output to that system. There are three types of compensators: lag, lead and lag-lead compensators. Adjusting a control system in order to improve its performance might lead to unexpected behaviour (e.g., poor stability or even instability by increasing the gain value).
She adds that using the word “should” can unwittingly lead to feelings of shame, as if they should have already known and done better. Dr. Danda points to one alternative: “I have some ideas ...
A lead–lag compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. It is a fundamental building block in classical control theory .
