In view of the multi-source uncertainty disturbance problem during flight control, attitude autopilot based on fuzzy linear active rejection control (F-LADRC) was proposed. A second-order controller designed to stabilize angle missiles, and frequency domain characteristics were analyzed. Firstly, it proved that expansion state observer (LESO) is convergent can achieve indifference estimation sy...

In healthy individuals, emotions modulate pain and spinal nociception according to a valence linear trend (ie, pain/nociception is highest during negative emotions and lowest during positive emotions). However, emerging evidence suggests that emotional modulation of pain (but not spinal nociception) is disrupted in fibromyalgia and disorders associated with chronic pain risk (eg, major depressi...

This paper proposes an improved predictive position control (IPPC) method based on the disturbance observer (DOB) for linear synchronous motor (LSM) to enhance tracking accuracy and robustness against parameter mismatches load disturbance. A soft constraint containing difference between errors their exponential convergence trajectory is developed cost function improve accuracy. Moreover, IPPC e...

In this paper a constructive method to determine and compute probabilistic reachable invariant sets for linear discrete-time systems, excited by stochastic disturbance, is presented. The samples of the disturbance signal are not assumed be uncorrelated, only bounds on mean covariance matrices supposed known. This allows consider nonlinear systems approximations effect filters disturbance. corre...

We propose a method to detect the onset of linear trend in a time series and estimate the change point T from the profile of a linear trend test statistic, computed on consecutive overlapping time windows along the time series. We compare our method to two standard methods for trend change detection and evaluate them with Monte Carlo simulations for different time series lengths, autocorrelatio...

Although linear trend removing has often been implemented as a routine preprocessing step in resting-state functional magnetic resonance imaging (RS-fMRI) data analysis, the spatial distribution of the magnitude of linear trend is still unclear. Further, it is interesting whether there will be any difference of the linear trend magnitude between different resting-states. For the first aim, we a...

This paper addresses an approximation-based anti-windup (AW) control strategy for suppressing the windup effect caused by actuator saturation nonlinearity in proportional–integral–derivative (PID) controlled systems. The effect of actuator constraint is firstly regarded as a disturbance imported to the PID controller. The external disturbance can then be modeled by a linear differential equatio...

In this paper, I find that real U.S. GDP is better characterized as a trend stationary Markov-switching process than as having a (regime-dependent) unit root. I examine the effects of both assumptions on the analysis of business cycle features and their implications for the persistence of the dynamic response of output to a random disturbance.
