摘要：Abstract Knock limit control is necessary for maximizing engine efficiency and avoid knock which can cause damage to the engine. In this paper, the stochastic properties of knock intensity signal are discussed and based on these characteristics, a closed-loop knock limit controller is proposed. Exponential moving average is applied to estimate both mean and reference of logarithm of knock intensity. According to the difference between mean and reference, the controller adjusts its control gain and output. Experiment validates the performance of the controller.
