Optimal control methods for drug delivery in cancerous tumour by anti-angiogenic therapy and chemotherapy. [PDF]
IET Syst Biol, 2021 Abstract There are numerous mathematical models simulating the behaviour of cancer by considering variety of states in different treatment strategies, such as chemotherapy. Among the models, one is developed which is able to consider the blood vessel‐production (angiogenesis) in the vicinity of the tumour and the effect of anti‐angiogenic therapy.

Fully probabilistic control for uncertain nonlinear stochastic systems
Asian Journal of Control, Volume 25, Issue 4, Page 2498-2507, July 2023., 2023 Abstract This paper develops a novel probabilistic framework for stochastic nonlinear and uncertain control problems. The proposed framework exploits the Kullback–Leibler divergence to measure the divergence between the distribution of the closed‐loop behavior of a dynamical system and a predefined ideal distribution.

IET Control Theory &Applications, Volume 17, Issue 10, Page 1381-1396, July 2023., 2023 A nonlinear optimal control problem is reduced to a sequence of timevarying linear quadratic optimal control subproblems. By using the approximating pseudospectral method, an numerical solution to the optimal control problem can be obtained. Convergence of the algorithm is also proved.

IET Renewable Power Generation, Volume 16, Issue 2, Page 416-434, 3 February 2022., 2022 Abstract This study deals with the comprehensive modelling, analysis, and control of a DC microgrid (MG) in islanded mode. The proposed DC MG comprises a wind turbine, a photovoltaic (PV) source, battery storage, DC/DC source, and load side converters with DC loads. To this aim, a circuit‐oriented modelling of the whole system is developed.

Gravity compensation and optimal control of actuated multibody system dynamics
IET Control Theory &Applications, Volume 16, Issue 1, Page 79-93, January 2022., 2022 Abstract This work investigates the gravity compensation topic, from a control perspective. The gravity could be levelled by a compensating mechanical system or in the control law, such as proportional derivative (PD) plus gravity, sliding mode control, or computed torque method.
