Class SineError.Relaxation

java.lang.Object

stella.util.SineError.Relaxation

Enclosing class:

SineError

private static final class SineError.Relaxation
extends Object

A class that simulates the reaction of the system to an offset. As long as the relaxation is active, this class return the current value of the individual relaxation process with getCurrentRelax(double). Once isFinished(double) returns true, no more changes in the relaxation will occur and the instance can be removed from the currently active relaxation list.

Field Summary

Fields

Modifier and Type	Field and Description
private double	attain The total offset this relaxation process should attain to.
private double	deadtime The deadtime of the process.
private double	speed The speed with which the system reaction during latency phase.
private double	t0 The time this relaxation was started.

Constructor Summary

Constructors

Modifier	Constructor and Description
private	Relaxation(double tstart, double total, double toff, double velocity) Constructs a new relaxation process whose current offset is determined by a function that returns zero during the deadtime and will return its full offset latency and total offset dependant after the deadtime.

Method Summary

Modifier and Type	Method and Description
double	getCurrentRelax(double t) Returns the current relaxation state of this process.
boolean	isFinished(double t) Returns true if this relaxation process is finished.

Field Detail

t0

private double t0

The time this relaxation was started.

attain

deadtime

private double deadtime

The deadtime of the process.

speed

private double speed

The speed with which the system reaction during latency phase.

Constructor Detail

Relaxation

private Relaxation(double tstart,
                   double total,
                   double toff,
                   double velocity)

Constructs a new relaxation process whose current offset is determined by a function that returns zero during the deadtime and will return its full offset latency and total offset dependant after the deadtime.

Method Detail

getCurrentRelax

public double getCurrentRelax(double t)

Returns the current relaxation state of this process. This is calculated using the starttime and the current time in the following way:

After the relaxation is finished, it should be removed from the currently active relaxation processes list.

isFinished

public boolean isFinished(double t)

Returns true if this relaxation process is finished. This depends on the time, speed and total offset to attain. After a relaxation process is finished, it always returns the total value and can be removed from the list of current active offsets.
