根据液压凿岩机参数调节的固有特征，在恒功率自动换档的基础上，建立了液压凿岩过程有级调节冲击能、冲击频率及无级调节推进力和转钎速度的全参数自适应最优控制数学模型；此外，根据有级调节的特性，提出了先采用逐个变量变步长试行登山法分级局部寻优、然后再取各级局部最优中的最佳控制为其全参数自适应最优控制的程序以及液压凿岩全参数自适应控制最终成为现实提供了可行的理论指导和实现方法． According to the inherent characteristics of hydraulic rock drill parameter adjustment, based on the constant power automatic shift, the full parameter self-adaptive optimality of stepwise adjustment impact energy, impact frequency, stepless adjustment propulsion and brazing speed of hydraulic rock drilling process is established Control mathematical model. In addition, according to the characteristics of step-by-step adjustment, it is proposed that the method of step-by-step variable climbing with step-by-step variable hill-climbing method should be adopted firstly, and then the optimal control of local optimum at all levels The program of excellent control and the full parameter adaptive control of hydraulic drilling finally become a reality to provide a feasible theoretical guide and realization method.
