Power Split Power Train Controller with ON/OFF

This controller operates as follows:

• it makes the ice deliver the average power needed by the power train
• it determines the optimal ice speed at which the requested power is delivered with minimum fuel consumption and asks the "gen" to control so that the ice opertes at that speed
• the vehicle motion is controlled acting on the "mot".
• a closed-loop SOC control avoids the battery do become too charged or discharged
• an ON/OFF control determines ICe switching OFF when the looad is to loow and switching it ON again when the requested power is sifnigicntly high. this normally reduces fuel consumpton.

So:

• powFilt Block filters the delivered power to obtained the power to ask the ICE to deliver
• toIceWref converts the power to be requested from the ICE by its maximum torque at the actual speed
• after a limiting block, this torque is the reference signal of a feedback; the corresponnding error controls the Gen torque.
• fbSOC sis the feedback for SOC control and socLoopGain is its gain
• hysteresis manages switching ON/OFF the ice.

Details of ice going to off (e.g. bringing its speed to zero) and to on (i.e. first making ice speed to rise, then start sending fuel) are not implemented.
