Modeling, Optimization and Control of Advanced Switched Inertance Hydraulic Converters

每个液压回路都浪费能源。最近的一项研究估计，美国液压设备的平均能效为21%，每年浪费的能源约为100亿升柴油。加拿大可以期望有类似的整体效率和相应的能源浪费。当为了控制流量或压力而通过控制阀对高压流量进行节流时，在液压回路中浪费的大部分能量都被浪费了。一项有潜力在这些电路的效率方面做出革命性改变的技术是开关惯性液压转换器（SIHC）。与节流阀不同，节流阀在减少流量或压力时损失能量，sihc将高压、低流量的输入转换为可控的低压、高流量的输出（反之亦然），将压力能高效地转换为流量能，而不是损失。如果在整个行业中应用，预计sihc将对全球化石燃料消费产生重大影响。这项拨款申请涉及这些设备的建模和优化，特别是与限制其实际实施的复杂波传播效应有关。

Every hydraulic circuit wastes energy. A recent study estimated the average energy efficiency of hydraulic equipment in the US at 21%, wasting energy on the order of 10 billion liters of diesel fuel yearly. Canada can expect to have a similar overall efficiency and proportionate waste of energy. Much of the energy wasted in hydraulic circuits is lost when high pressure flows are throttled by control valves in order to control flow or pressure. A technology that has potential to make a revolutionary change in the efficiency of these circuits is the Switched Inertance Hydraulic Converter (SIHC). Unlike throttling valves, which lose energy when reducing flow or pressure, SIHCs convert a high-pressure, low-flow input into a controlled low-pressure, high-flow output (or vice versa), converting pressure energy into flow energy at high efficiency rather than losing it. If applied across the industry, SIHCs can be expected to make a significant impact in the worldwide consumption of fossil fuel. This grant application is concerned with modeling and optimization of these devices, particularly to do with the complex wave propagation effects that limit their practical implementation.
