Control of the process of ACC/DEC (Acceleration/Deceleration) is one of most complicated problems in CNC system development. With the increase of acceleration and velocity in high-speed, high-precision CNC system, discontinuousness of acceleration will result in vibration, impact and debasing of position accuracy. The excellent ACC/ DEC control can solve these problems and improve the positioning precision. In this paper, S curve ACC/DEC algorithm is deeply studied, through comparison with other algorithms; its proved to be an efficient way in advanced CNC system. Usually, such kind of algorithm requires high-speed processor. However realization based on SCM (Single Chip Machine) is proposed in this paper. Through simulation, the result shows that the algorithm works well. Finally practical tests are carried out in Panasonic Minas A5 servo motor which indicates the control system is effective and accuracy.

Validation of the design is a milestone in development cycle of a system. Actual testing of the component is an ultimate means to carry out the design validation. It is required to perform testing and verify the hardware functionality in order to gain confidence in operational implementation. Data acquisition during the performance acceptance testing is an essential requirement for any design validation by testing. If the system dynamics are changing rapidly the need for high speed measurements becomes essential such as in the case of jet engine fuel control system which is a dynamical system with fast transients of the order of few milliseconds. A better acquisition hardware and processing algorithm helped to reduce the latency in the acquired signals. Further, since there are multiple design test centers for fuel control system development, portability of data acquisition system aided in validating the subsystem with same standard of preparation at all centers prior to system integration.

BLDC motors are characterized by electronic commutation, which is performed by using an electric three-phase inverter. The direct control system of the BLDC motor consists of double loops; including the inner-loop for current regulating and outer-loop for speed control. The operation of the current controller requires feedback of motor currents; the conventional current controller uses two current sensors on the ac side of the inverter to measure the currents of two phases, while the third current would be accordingly calculated. These two sensors should have the same characteristics, to achieve balanced current measurements. It should be noted that the sensitivity of these sensors changes with time. In the case of one sensor fails, both of them must be replaced. To overcome this problem, it is preferable to use one sensor instead of two. The proposed control system is based on a deadbeat predictive controller, which is used to regulate the DC current of the BLDC motor. Such a controller can be considered as digital controller mode, which has fast response, high precision and can be easily implemented with microprocessor. The proposed control system has been simulated using Matlab software, and the system is tested at a different operating condition such as low speed and high speed.

Electromagnetic actuator systems composed of an induction servo motor (ISM) drive system and a rice milling machine system have widely been used in agricultural applications. In order to achieve a finer control performance, a witty control system using a revised recurrent Jacobi polynomial neural network (RRJPNN) control and two remunerated controls with an altered bat search algorithm (ABSA) method is proposed to control electromagnetic actuator systems. The witty control system with finer learning capability can fulfill the RRJPNN control, which involves an attunement law, two remunerated controls, which have two evaluation laws, and a dominator control. Based on the Lyapunov stability principle, the attunement law in the RRJPNN control and two evaluation laws in the two remunerated controls are derived. Moreover, the ABSA method can acquire the adjustable learning rates to quicken convergence of weights. Finally, the proposed control method exhibits a finer control performance that is confirmed by experimental results.
