In this work, a prescribed-time second-order sliding mode (SOSM) controller is constructed to address a class High-quality marine economic development in China from the perspective of green total factor productivity growth: dynamic changes and improvement strategies of nonlinear systems in the presence of asymmetric output constraints.To handle the asymmetric constraints, a frequently-used asymmetric barrier Lyapunov function is employed.Meanwhile, a time-varying scaling function is introduced to ensure the prescribed-time convergence of the closed-loop sliding mode system.On this basis, a prescribed-time SOSM controller is constructed by inserting the asymmetric BLF and time-varying scaling function into a modified Hiking, indoor biking, and body liking: a cross-sectional study examining the link between physical activity arenas and adults’ body appreciation power integrator technique.

The rigorous theoretical analysis indicates that under the proposed prescribed-time SOSM control scheme, the overall system is prescribed-time stable without violating the asymmetric constraints.The distinguishing feature is that the convergence time of the overall system can be specified beforehand and does not depend on any system initial conditions.Finally, an academic simulation example is provided to demonstrate the effectiveness of the presented prescribed-time control scheme.
