In this paper, a soft CNCS (Computerized Numerical Control System) works on Windows-XP operating system is presented. The comparison between soft CNC and traditional CNC system is discussed. The structure of soft CNC system is introduced as follow. The realizations of each real time module, such as real time path planning and interpolation, real time close-loop controller, real time safety detection, are introduced in detail. The real time tasks are based on a real time kernel. In the end, an application of the soft CNC system is realized on a 3-axis milling machine. The machining result shows it works well.

The existing hydraulic pressure control fault diagnosis system is effective on fault detection, but the fault isolation capability is bad. In order to improve the capability of the fault isolation, the artificial neural network (ANN) is used in the fault diagnosis system. Aimed at the representative diagnosis of the hydraulic pressure control system, the three layers feedback network is adopted, the basic theory of conjugate gradient BP neural network is explained in detail, and the key techniques are introduced. Five types of typical faults of hydraulic pressure control system can be distinguished easily by it, the faults diagnosis efficiency is higher 30% than ever and the fault diagnosis capability is better 80% than before.

On the basis of analyzing the shortcomings of the current technics for grooves machining, this paper deals with the development of Numerical Control System for machining of grooves in automobile synchronization regulator sleeve, which holds first-rate technics. In order to improve efficiency and precision of grooves machining and reduce cost of the cutter, Hypocycloid-based technique together with interpolation is introduced and studied. With IPC as system platform and PMAC (Programmable Multiple-Axes Controller) as the controlling center of the system, the open architecture of “PC-Based” is used in the CNC system and the framework of the CNC hardware is developed. According to the ideas of modularization and real-time multi-task scheduler, the CNC software system is carved into many modules and the framework of the CNC software is developed.

A robust parameter-depended reduced order(RPRO) fault detection filter(FDF) is designed. Contrary to the parameter-depended uncertainty system, the order of the linear matrix inequalities is reduced, then the RPRO fault detection and fault isolated filters are constructed. Then a RPRO fault isolation filter is designed for occurrence of both actuator fault and sensor fault in the aerocraft’s closed-loop control system, and fault diagnosis system is structured based on the fault isolation filters. Through the output of the fault diagnosis system, we can alarm the fault timely and the advantages of this approach are highlighted.
