Comment of some PID_controller.java

Comment of some Methods

 
A set Method for integral value is necessary to optimize control PID_controller.java public void setIntg(short setValue)
Demonstrate the necessity of throw exception if the integral value of PID controller has an overflow. PID_controller.java (intValNew ^ intgVal ) & 0x80000000 ) == 0x80000000 ...
Tuning of values, the normalize range of controller is -20000 to 200000, the actuator has an output range from -10000 to 10000, adaption and limitiation MainController.java if(yOut > 19999)
{ yOut = 19999; ...
... setMotorVoltage((short)(yOut>>1));
But demonstrate a difficult software error so that an exception is thrown in PID_controller MainController.java //pidCtrl1.setIntg(yOut); commented, than exception
Trimming values so that the error occurs MainEmulation.java disturbance1 = 0.9 + 0.5*Math.sin( ...
MainEmulation.c mainEmulation.nAmplificationActuator = 0.45F;
catch the exception also in C MainEmulation.c

TRY{...}_TRY ...

printStackTrace_ExceptionJc(exc, stdout);
Some adaption errors in ExceptionJc ExceptionJc.c

ExceptionJc* exception = &stacktrace->tryObject->exc;
