In the classical infectious disease compartment model, the parameters are fixed. In reality,
the probability of virus transmission in the process of disease transmission depends on the …

In this paper, a unified symplectic pseudospectral method for motion planning and tracking
control of 3D underactuated overhead cranes is proposed. A feasible reference trajectory …

The symplectic wave-based method is extended to the free and forced vibration analysis of
thin orthotropic circular cylindrical shells with arbitrary boundary conditions. The key of this …

As an efficient and safe dispatching scheme is of great importance to ensure the
effectiveness and safety of personnel on the Aircraft Carrier, and the towed aircraft system …

We formulate a mathematical model to explore the transmission dynamics of human
papillomavirus (HPV). In our model, infected individuals can recover with a limited immunity …

In this paper, we propose an iterative framework to solve optimal control for nonlinear
proportional state-delay systems. The successive convexification technique is first …

In this paper, optimal control problems governed by linear discrete‐time descriptor
noncausal systems (with quadratic input variables) are investigated in order. A descriptor …

In the present paper, a robust pseudospectral method for efficient numerical solution of
nonlinear optimal control problems is presented. In the proposed method, at first, based on …

Time-delays are often involved in modelling biological processes, which arise more
difficulties for the control task. In fact, once the control goal is given, a constrained optimal …

This paper proposes a novel symplectic pseudospectral iteration framework for the
nonlinear optimal control problem (OCP) of a pantograph delay system with inequality …
