Detecting the cyber-attacks in intelligent connected vehicle systems (ICVS) precisely is essential for ensuring the personal security and normal communication of ICVS. This paper gives a solution to estimate cyber-attacks for ICVS. A distinctive approach is represented to take advantage of an augmented states technique of ICVS. What's more, a nonlinear fuzzy unknown input observer (FUIO) to estimate dynamics asymptotically of ICVS that is under cyber attacks is proposed. For the FUIO design, the dynamics model ICVS can be written in the particular Takagi-Sugeno (TS) fuzzy model in the form of nonlinear consequence. Particularly, the application of TS theory enables the implement of differential mean value theorem (DMVT), which attaches great importance to the simplification of perplexing premise variables that are unmeasured. Furthermore, a linear matrix inequalities is given by exploiting TS theory, which can not only satisfy the sufficient conditions of FUIO designing, but also be easily solved by a series of techniques such as convex optimization. The simulation figures demonstrate great effectiveness of the formulated FUIO design.

Implementing dynamic locomotion behaviors on legged robots requires a high-quality state estimation module. Especially when the motion includes flight phases, state-of-the-art approaches fail to produce reliable estimation of the robot posture, in particular base height. In this paper, we propose a novel approach for combining visual-inertial odometry (VIO) with leg odometry in an extended Kalman filter (EKF) based state estimator. The VIO module uses a stereo camera and IMU to yield low-drift 3D position and yaw orientation and drift-free pitch and roll orientation of the robot base link in the inertial frame. However, these values have a considerable amount of latency due to image processing and optimization, while the rate of update is quite low which is not suitable for low-level control. To reduce the latency, we predict the VIO state estimate at the rate of the IMU measurements of the VIO sensor. The EKF module uses the base pose and linear velocity predicted by VIO, fuses them further with a second high-rate IMU and leg odometry measurements, and produces robot state estimates with a high frequency and small latency suitable for control. We integrate this lightweight estimation framework with a nonlinear model predictive controller and show successful implementation of a set of agile locomotion behaviors, including trotting and jumping at varying horizontal speeds, on a torque-controlled quadruped robot.
