Re: Another method of gyro integrating.

Hi Nigma (and Lubin)... The Integrator (Discrete-Time has a Cte = 0.003 i.e. Time Cte = 1/0.003 = 333s. Analyze the (SubSystem Feedback) from (In = Output SubSys3) to the (Out= Summing point) from Acc and Gyro: The G = 0.003 represents the “speed of integration” - very slow; The Feed back is Unity -...

Re: Did anyone implement a controller in dsPIC by this toolbox?

I have just derived the controller: It present a Proportional Derivative dynamics. This Gain -koefficient in the first intrgrator feed back must be negative. ...in both the Plant and the controller. The controller presented is not performing PI. If the Gain is negative then we have a first order fi...

Re: Did anyone implement a controller in dsPIC by this toolbox?

The controller model presented has problem with the Gain 3; It must be negative...
Gain 3 and Gain 2 MUST be negative...
...and do not try any positive feedback design in your systems unlesss you are designing Variable Structure System Design...
