先前的研究表明，高性能发动机控制器可以与自动变速器的电子控制装置结合使用，以提高换档质量。由于汽车发动机的高度非线性特性以及对设计稳健性的需求，滑动控制是一种可能的选择。然而，汽车发动机的标准滑动推导会导致不切实际的控制律。可以使用导出滑动控制的替代方法，将状态之一定义为合成控制。假设综合控制作为输入，导出控制律。然后必须导出第二定律来控制合成状态。对于汽车发动机来说，两个表面控制器比标准控制律更简单、更鲁棒。通过利用发动机只有一个输出的事实，可以开发一种协调火花和节气门输入的方法，以利用它们各自的优势。结合火花/油门控制的两个表面控制律的实验实现验证了该算法的性能和鲁棒性。
Previous research has shown that high performance engine controllers could be used in conjunction with electronic controls on automatic transmissions to improve shift quality. Due to the highly nonlinear nature of automotive engines and the need for robustness of the design, sliding control is a likely choice. However, a standard sliding derivation for an automotive engine results in an unpractical control law. An alternate method of deriving sliding controls can be used that defines one of the states to be a synthetic control. A control law is derived assuming the synthetic control as the input. A second law must then be derived to control the synthetic state. For automotive engines, the two surface controller is be much simpler and more robust than the standard control law. By taking advantage of the fact that the engine only has one output, it is possible to develop a method of coordinating the spark and throttle inputs in such a way as to take advantage of their respective strengths. Experimental implementation of the two surface control law with combined spark/throttle control has verified the performance and robustness of this algorithm.
