Aiming at the problem of forward tracking guidance munitions with missile body characteristics intercepting maneuvering targets, and to improve the hit accuracy of forward tracking guidance system, this paper proposes an adaptive super-twisting sliding mode forward tracking guidance algorithm considering the impact of first-order overload characteristics of missile body and input saturation limitation. Firstly, the nonlinear model of the guidance system is made by the kinematic relation for projectile-target, the principle for the forward tracking interception, the overload characteristic of the missile body, and the input saturation limitation. Secondly, a finite time interference observer (FTIO) is adopted to accurately estimate the nonlinear interference in the guidance system, furthermore, an adaptive super-twisting algorithm for slide mode control is used to design the forward tracking guidance algorithm considering the characteristics of the projectile body. Finally, the results by simulation indicate the adaptive super-twisting slide mode for forward tracking guidance algorithm considering characteristics of the projectile body designed in this paper has better-hit accuracy.

“…In [4], the double power reaching law is adopted to design pre-tracking intercept guidance law, which weakens chattering with a closed-loop system to a certain extent. In [5], the fractional-order control theory, which has strong robustness, is used to investigate the forward-tracking guidance algorithm.…”

To solve the problem of forward tracking guided munition intercepting high-speed maneuvering targets and to ensure the guidance precision of forward tracking interception system, a novel forward tracking guidance algorithm based on the non-singular fast dynamic surface sliding mode is proposed in this study, which considers the influence of the dynamic characteristics for munition in the guidance system. Firstly, the influence of the manoeuvering ability for munition in the guidance system is considered, and then on the basis of the relative motion relation of the munition and the principle of forward tracking and interception, a forward tracking guidance system model with dynamic characteristics is established. Secondly, a nonlinear state observer is used to calculate the interference in the system. On this basis, a forward-tracking guidance law with dynamic characteristics is designed by using a non-singular fast dynamic surface sliding mode control method. Finally, the numerical simulation results show that compared with the traditional algorithm, the non-singular fast dynamic surface sliding mode forward tracking guidance law with dynamic characteristics can not only meet the design requirements but also has better guidance accuracy.

“…In the FOSMC, the improvement in terms of chattering reduction [37] and fast response [38][39][40][41][42][43], is achievable through the concept of fractional order calculus [44]. With these advantages, the FOSMC was utilized in several applications such as aerospace [45][46][47][48], missile guidance [49][50][51], automotive [52][53], robotic [40,[54][55][56][57], energy, and power systems [58][59][60][61]. Also, the SEIR epidemic model's vaccination control policy was established by the FOSMC [62][63].…”

The Hepatitis-B (HBV) epidemic's dynamic can be presented as a compartment model. Determining the HBV epidemic control strategy can be considered a nonlinear feedback control problem. The sliding mode controller (SMC) is an effective feedback control method for controlling the dynamical system under disturbances. Recently, the SMC based on fractional order calculus can provide preferable characteristics for a control system such as robustness and convergence rate. In this study, the HBV epidemic system's control policy is proposed using the fractional order sliding mode controller (FOSMC). The control policy with multiple measures including vaccination, isolation, and treatment is formulated to manipulate the susceptible and the infected subpopulations to the desired level. The Lyapunov-based approach is proven for stability analysis. The control policy is applied to the simulation example to verify the feasibility of the proposed FOSMC method. The simulation results are compared with those of the integer order SMC. By the proposed method, the results reveal that the susceptible and infected subpopulations are driven to the desired levels under disturbances with a higher convergence rate compared to that of the integer one. Moreover, the proposed FOSMC method can reduce the chattering occurrence which is the primary drawback of the SMC method.
