This article uses the theory and method of fuzzy,optimizes the schemes and parameters design of big mining system and discusses the application of the theroy and method of fuzzy to the problem about how to determine mining design schemes and parameters.
The article introduces working principle,construction characters,main technology parameters of a new style hydraulic prop_internal circulation external applied force,and makes design parameters to manual loading pump.
In addition, there are only two design parameters, which are the predictive period and control order, so it is easy to implement and test in practical use.
It is proven that the proposed control scheme guarantees that all the variables in the closed-loop system are bounded and the mean-square tracking error can be made arbitrarily small by choosing some design parameters appropriately.
Using the differentials of a stiffness matrix to design parameters, a method for calculating the sensitivity of natural frequency is presented.
The numerical simulation results indicate that the design parameters have an impact on the frequency characteristics of the compliant mechanisms and the proposed method is more accurate and convenient for analyzing frequency characteristics.
The issues concerning the problem of choosing the main design parameters of a multistage spacecraft are touched upon.
