Localization and mapping with heterogeneous multisensor fusion have been prevalent in recent years. To adequately fuse multimodal sensor measurements received at different time instants frequencies, we estimate the continuous-time trajectory by fixed-lag smoothing within a factor-graph optimization framework. With formulation, can query poses any corresponding to measurements. bound computation...

This paper presents a control synthesis method for a class of semi-active seat suspension systems with input time delay, parameter uncertainties and actuator saturation. A vertical vibration model of human body is employed and put together with the plant of the seat suspension system in order to gain a better insight of the control performances. The H∞ performance is used to measure ride comfor...

abstractthe understanding of water resources for the purpose of ground and surface water management as two inseparable systems is great importance. in this study by examining the time series of climatic variables (precipitation), hydrological (flow and consume) and the level of water table, the parameters associated with each other and with fluctuating water table can be realized. there was a d...

A large proportion of industrial systems are represented by linear time-invariant transfer functions. The proportional-integral -derivative (PID) controller is one of the most widely used functions. The lead-lag controller is a more practical alternative. Lead-lag-like controller can be lead-lead, lag-lead or lag-lag controller. This paper focused on the design of lead-lag-like controller by op...
