This paper presents the design of discrete-time model reference learning control of linear system for tracking aperiodic signal while rejecting periodic disturbance. The design integrates model reference control (MRC) and Iterative Learning control (ILC) in order to achieve the desired objective. The use of MRC makes tracking any reference signal is possible, while ILC is used to eliminate the periodic disturbance. The proposed design is simulated on LTI system with repetitive output disturbance. model reference learning control with several ILC learning gains are simulated. It is shown that ILC learning gain can be tuned to determine the convergence rate and stability of the whole system. Simulation results indicate that the accurate tracking of aperiodic reference can be achieved as long as the plant and disturbance models are accurately known.

The traditional state feedback control method needs longer adjustment time and needs longer time to stably track the changes of the flight state commands. Aiming at the above situation, a LPV model reference control method is developed in this paper. Firstly, considering the changes of the flight states of the hypersonic vehicle, the control law of the hypersonic vehicle based on LPV model reference control method is designed according to the characteristics of the longitudinal model of the aircraft. Then, the singular value decomposition is used to solve the controller’s coefficient matrix and the controller’s state feedback gain is solved by the linear matrix inequality. Under the action of the controller, the actual output of the model converges to the output of the reference model. Finally, effectiveness of the controller is verified by the simulation results. The comparison between the designed controller and the traditional state feedback controller shows that the designed controller has shorter adjustment time and smaller overshoot.

This paper proposes a linear parameter varying (LPV) model reference-based control for fixed-wing unmanned aerial vehicles (UAVs), which achieves agile and high performance tracking objectives in extended flight envelopes, e.g. when near stall or deep stall flight conditions are considered. Each of the considered control loops (yaw, pitch and airspeed) delivers an error model that can be reshaped into a quasi-LPV form through an appropriate choice of the scheduling variables. The quasi-LPV error models are suitable for designing error feedback controllers using linear matrix inequalities (LMIs), which are derived within the quadratic Lyapunov framework. Simulation results are used to show the effectiveness of the proposed approach. © 2017

In this paper, a model reference control based inertia emulation strategy is proposed. Desired inertia can be precisely emulated through this control strategy so that guaranteed performance is ensured. A typical frequency response model with parametrical inertia is set to be the reference model. A measurement at a specific location delivers the information of disturbance acting on the diesel-wind system to the reference model. The objective is for the speed of the diesel-wind system to track the reference model. Since active power variation is dominantly governed by mechanical dynamics and modes, only mechanical dynamics and states, i.e., a swing-engine-governor system plus a reduced-order wind turbine generator, are involved in the feedback control design. The controller is implemented in a three-phase diesel-wind system feed microgrid. The results show exact synthetic inertia is emulated, leading to guaranteed performance and safety bounds.

A new model reference control architecture: Stability, performance, and robustness

In this paper, we develop a new model reference control architecture to effectively suppress system uncertainties and achieve a guaranteed transient and steady-state system performance. Unlike traditional robust control frameworks, only a parameterization of the system uncertainty given by unknown weights with known conservative bounds is needed to stabilize uncertain dynamical systems with predictable system performance. In addition, the proposed architecture's performance is not dependent on the level of conservatism of the bounds of system uncertainty. Following the same train of thought as adaptive controllers that modify a given reference system to improve system performance, the proposed method is inspired by a recently developed command governor theory that minimizes the effect of system uncertainty by augmenting the input signal of the uncertain dynamical and reference systems. Specifically, a dynamical system, called a command governor, is designed such that its output is used to modify the input of both the controlled uncertain dynamical and reference systems. It is theoretically shown that if the command governor design parameter is judiciously selected, then the controlled system approximates the given original, unmodified reference system. The proposed approach is advantageous over model reference adaptive control approaches because linearity of the uncertain dynamical system is preserved through linear control laws, and hence, the closed-loop performance is predictable for different command spectrums. Additionally, it is shown that the architecture can be modified for robustness improvements with respect to high frequency content due to, for example, measurement noise. Modifications can also be made in order to accommodate actuator dynamics and retain closed-loop stability and predictable performance. The main contribution of this paper is the rigorous analysis of the stability and performance of a system utilizing the command governor framework. A num

Robotic manipulators have been widely used in many arenas;when the robotic arm performs positioning, traditional controller (e.g., PID controller) has the problem of not being able to compensate the payload variations, i.e., when the end-effector of the robotic arm grasps different payload masses, as most applications require, the output of joint motion will vary, which decreases end-effector positioning accuracy of the robotic arm system. Based on the model reference control approach, the payload variation effect can be solved effectively and therefore, to further improve the robotic arm positioning accuracy performance.

Servo drive systems require a fast dynamic response for position control applications. Conventional cascade control structure has sluggish response due to bandwidth limitations on speed and current control loop. To achieve a fast output response, model reference adaptive control methods can be used to remove the dynamics of inner control loops. In this paper, feed-forward signals are generated using model predictive control which is combined with the conventional cascade structure. Using this approach, a fast transient response and satisfactory tracking ability can be achieved. The proposed control configuration is verified by the simulation results.

Novel model reference-based hybrid decoupling control of multiport-isolated DC-DC converter for hydrogen energy storage system integration

引用

JOURNAL OF ENERGY STORAGE 2025年 109卷

作者： Oyewole, Oyedotun E. Abdelaziz, Ali A. Abdelsalam, Ibrahim Bari, Eugene Ahmed, Khaled H. Univ Strathclyde Dept Elect & Elect Engn Glasgow G1 1XQ Scotland Arab Acad Sci Technol & Maritime Transport Cairo Campus Cairo EG Egypt Ecomar Prop Ltd 32 Stand Way Fareham PO16 8XG England

Hydrogen energy storage systems (HESS) are increasingly recognised for their role in sustainable energy applications, though their performance depends on efficient power electronic converter (PEC) interfaces. In this paper, a multiport-isolated DC-DC converter, characterised by enhanced power density, reduced component count, and minimal conversion stages, is implemented for HESS applications. However, the high-frequency multiwinding transformer in this converter introduces cross-coupling effects, complicating control and resulting in large power deviations from nominal values due to step changes on other ports, which adversely impact system performance. To address this issue, a novel model reference-based decoupling control technique is proposed to minimise the error between the actual plant output and an ideal decoupling reference model, which represents the cross-coupling term. This model reference-based decoupling control is further extended into a hybrid decoupling control technique by integrating a decoupling matrix, achieving more robust decoupling across a wider operating region. The hybrid decoupling technique mathematically ensures an improved control performance, with the cross-coupling term minimised through a proportional-derivative controller. The proposed hybrid decoupling controller achieves a maximum power deviation of <3 % under various conditions, outperforming the conventional inverse decoupling matrix technique, which typically exhibits higher deviations under similar conditions. The effectiveness of the hybrid decoupling control is validated through simulations and experimental results, demonstrating significant improvements in decoupling performance.
