Approximate dynamic programming is used to solve optimal tracking problems in switched systems with controlled subsystems and fixed mode sequence. Two feedback control solutions are generated such that the system tracks a desired reference signal, switching instants sought. Simulation results provided illustrate effectiveness of solutions.

Magnetic Resonance (MR) imaging-based motion and deformation tracking techniques combined with finite element (FE) analysis are a powerful method for soft tissue constitutive model parameter identification. However, deriving deformation data fromMR images is complex and generally requires validation. In this paper a validation method is presented based on a silicone gel phantom containing contr...

This paper proposes a data-driven Iterative Reference Input Tuning (IRIT) algorithm that solves a reference trajectory tracking problem viewed as an optimization problem subjected to control signal saturation constraints and to control signal rate constraints. The IRIT algorithm incorporates an experiment-based stochastic search algorithm formulated in an Iterative Learning Control (ILC) framew...

This paper discusses a model reference adaptive sliding-mode control of the sensorless vector controlled induction motor drive in a wide speed range. The adaptive speed controller uses on-line trained fuzzy neural network, which enables very fast tracking of the changing speed reference signal. This adaptive sliding-mode neuro-fuzzy controller (ASNFC) is used as a speed controller in the direct...

The Multiplexed Binary Offset Carrier (MBOC (6, 1)) signal is adopted to provide agreed [1], [2] common power spectral density for Galileo E1 Open Service (OS) and GPSIII L1C signals. In MBOC, a small amount of energy from a BOC signal with higher subcarrier frequency (i.e. BOC (6, 1)) is linearly added to the portions belong to the previous common baseline signal (i.e. BOC (1, 1)) to improve t...

This paper develops and experimentally validates a 3D-printed snake robot prototype. Its structure is designed to allocate limited room for each functional module (including an external power module, battery power module, the wireless control and transmission module and some detective sensors), so as to ensure the snake robot works in different environments. In order to control and track the sn...

When active radar and <span>sonar systems are used for target detection tracking, boosting detection, tracking efficiency is the most important challenge in real-time reverberation. To eliminate reverberation when transmitting linear frequency modulated (LFM) signals, this study employs time series techniques such as autoregressive (AR), moving average (MA), (ARMA). The primary purpose of...
