Abstract: A system includes an input selection module, a multiplier selection module, a multiplier module, an adding module, a plurality of accumulators, and an estimation module. The input selection module selects input signals including a duty cycle signal and current and voltage signals of a power supply. The multiplier selection module selects inputs from sine and cosine generator. The multiplier module multiplies the selected input signals by the inputs from the sine and cosine generator to generate products. The adding module adds the products to generate sums. The plurality of accumulators accumulates the sums. The estimation module estimates values of a plurality of components including an inductance, a capacitance, and a resistance of the power supply based on the sums accumulated in the plurality of accumulators.

Abstract: An apparatus for indicating and controlling the vehicle speed and load of a mobile foliage chopping machine. As rotational speed of the chopping drum increases over its permissible minimum, a vehicle increasing speed control is carried out. Correspondingly, a decrease in speed due to increase in the working load of the chopping drum is compensated by a reduction of gear transmission of the driving machinery. Thus, the adjusted speed is held but in case of chopping drum overload, when rotational speed of the drum starts to fall below the permissible minimum, the vehicle speed control is discontinued, i.e., a speed decreasing intervention is done, therefore the permissible working load of chopping machine is held, while overload is avoided.
