The paper proposes a new measurement method of angular acceleration for photoelectric servo turntable. Piezoelectric angular acceleration sensor is used to measure angular acceleration directly
Adaptive FIR filter based on LMS algorithm is established on DSP
by which angular acceleration signal can be filtered and corrected errors adaptively
then angular acceleration signals can be measured adaptively. This method avoids measurement errors and calculation noise by computing angular acceleration indirectly
thus improving measurement precision and making measurement results better than traditional methods. The gotten angular acceleration can be sent to servo control mechanism as feed forward control signals to improve control effects of servo turntable significantly. 2011 IEEE.

A computer control system is proposed which is based on hardware-in-loop(HWIL) simulation test system. As an important sub-system in simulation test system
the reality is the focus of the simulation system. The construction of the computer control system for laser warning based on HLA Distributed Simulation. By combining the outer clock and time stamp for data frame
data interaction is triggered by outer clock
the simulation process is propelled. The simulation terminal devices are also controlled by the outer clock. The simulation test is done by the above method. The result shows that the data interaction time less than lms
and it meet the need of reality for control
so it is effective. 2010 IEEE.

Stable platform is a complicated nonlinear system. The common PID control can not meet the requirement of high precision and fast response. The adaptive inverse control was introduced in the system of stable platform. Based on it
the system utilize its character of open circle to improve system capability. In the model building to object model and object inverse model
the NARX network is used. The algorithm uses the least square method instead of least square(LMS) to identify the parameters and design the control. The simulation results show several advantages of this control strategy
such as sensitive response
non-overshoot
good anti-disturbance
and minimal stable error
and showed dynamic/static performance was superior to those of conventional PID method. 2008 IEEE.

Classical methods for designing a controller depend on the accuracy of system model. However
plant's models and other parts in a physical system can not accurately represent all possible dynamics. Thus the controller designed is usually not the optimal one. In this article
a new
simple adaptive control method
which combines the classical frequency domain method with the neural network theory
is proposed. Firstly
we can obtain a controller using classical method. Secondly we use the coefficients in digitized controller equation as the initial values of an Adaline network. Finally
LMS learning rules is used to adjust the weights adaptively. Experimental results show that this method is very effective in improving the performance of conventional controller. 2006 IEEE.
