Purpose Trajectory tracking is an important issue to underactuated unmanned surface vehicles (USVs). However, parametric uncertainties and environmental disturbances bring great challenges to the precise trajectory tracking control of USVs. This paper aims to propose a robust trajectory tracking...

The hybrid heating system consisting of loop heat pipe solar collector (LHPSC) and ground source heat pump (GSHP) was proposed to maintain greenhouse temperature in Harbin (the coldest provincial capital of China) in this paper. The thermal model was developed to predict transient greenhouse and...
