Class RunningState

java.lang.Object

org.lsst.ccs.subsystems.fcs.simulation.RunningState

All Implemented Interfaces:

EngineState

public class RunningState
extends Object
implements EngineState

This is the concrete state where we know what to be done when the engine is in the state "running". Not used for single-filter-test test bench. This is old stuff when I tried to implement State pattern. Not sure I will continue to use that in the next version of FCS.

computeDisplacement

public double computeDisplacement(Motor motor,
                         double period,
                         RunningWay runningWay)

Computes the displacement (rotation angle or position) for this engine state during a time period. It can be positive or negative according to the running way.

Specified by:

computeDisplacement in interface EngineState

Parameters:

motor -

period -

runninWay -

Returns:

error

public String error(Motor motor)

Specified by:

error in interface EngineState

go

public String go(Motor motor,
        double t,
        RunningWay runningWay)

Engine stays in state running when it is running and it receives the command go.

Specified by:

go in interface EngineState

t - : in milliseconds

runningWay - rotation way

stop

public String stop(Motor motor)

It goes to "stop" when asked.

Specified by:

stop in interface EngineState
