Performance Study of A Deep
Space Communications System with Low-Density
Parity-Check Coding under Solar Scintillation
Qi Li, Liuguo Yin, Jianhua Lu
Abstract: The communication link is the only
way for space probe to receive telecommand data from
and return telemetry information to the control
center on the earth. The design of deep space
communication system has lots of challenging
problems. For example, the solar scintillation
effects can be significant for deepspace
telecommunication links during superior solar
conjunction. In this paper, the design and
application of low-density parity-check (LDPC)
coding scheme for deep space communication under
solar scintillation condition is studied. In
particular, the deep space communication channel
under solar scintillation condition is modeled as a
kind of Rician Channel that characterized by
scintillation index, and the LDPC codes are
optimized under such kind of channel mode to improve
the bit-error rate (BER) performance. Simulation
results reveal that compared with the convolutional
codes the proposed LDPC codes could obtain 2.4 db
and 2.5 db coding gain at 8.4 GHz (X-band) and 32
GHz (Ka-band), respectively. Moreover, simulation
results also show that the deep space communication
system with LDPC codes is much less sensitive to
scintillation fading that that with convolutional
codes.

Model Predictive Control for
Networked Control Systems with Random Data Dropouts
Eva Miklovicova, Marian Mrosko
Abstract: In this paper, the model predictive
control for the networked control systems is
proposed. The problem of data dropouts in the sensor
controller link when the controller does not receive
new feedback data is treated. As in predictive
control design the sequence of future control
actions up to a given horizon is calculated at each
sampling time, the natural idea is to use not only
the first control action, but also other terms of
the control sequence, in case the sensor data at
next sampling times are not available. From the
implementation point of view there are two or more
control laws (depending on the number of lost output
samples) which are switched arbitrarily fast. A
sufficient stability condition for this switched
control system is derived using the concept of
quadratic stability. The effectiveness of the
proposed control strategy is demonstrated by control
of a simple laboratory plant.

Wireless Network Effect on PI
and Type-2 Fuzzy Logic Controller
Michal Blaho, Martin Urban, Peter Fodrek, Martin
Foltin
Abstract: With usage of data networks in
control new area of research known as networked
control systems was presented. Many communication
medias and protocols can provide new possibilities
in practical implementation. Professional solutions
like PROFINET or IWLAN are followed with cheaper and
popular networks like ZigBee or CAN bus. Recently,
much attention has been paid to the wireless
networks. ZigBee wireless networks are very popular
for many advantages. Multiple control methodologies
and practical applications have been developed for
this kind of network. Applications must deal with
negative effect of ZigBee network like network
overload or packet dropout. In this paper we
threated network disadvantages as uncertainty and we
reduced them with type-2 fuzzy logic controller. We
compared results with PI controller using Matlab and
TrueTime environments.
