Title: Control and Coordination of Unicycles: Exploring the Fully Actuated System Approach
Abstract: The unicycle model serves as a simple yet powerful representation with wide implications in practical vehicle systems, encompassing differential drive robots, Ackermann-steered vehicles, among others. Simultaneously, it stands as a quintessential non-holonomic system, posing significant challenges in designing continuous stabilizing controllers. This talk aims to delve into existing efforts towards achieving stabilization and path-following control for the unicycle model, along with addressing coordination control for multiple unicycles. Furthermore, it explores the possibilities and intricacies associated with employing the fully actuated system approach, highlighting potential avenues and hurdles that need to be navigated.

Title: Output-Feedback Adaptive Boundary Control of Distributed Parameter Systems
Abstract: Distributed parameter systems, which are described by partial differential equations, widely exist in aerospace engineering, bioengineering, chemical engineering, and electrical engineering. Over the past decades, the control issues for distributed parameter systems have attracted considerable attention. In particular, the output-feedback adaptive control of distributed parameter systems is very challenging due to limited sensor measurements, unknown spatially varying parameters, and infinite-dimensional coupled dynamics. This talk will introduce some recent results on output-feedback adaptive boundary control for several classes of distributed parameter systems. The basic tools include observer canonical form, swapping identifier, and infinite-dimensional backstepping approach.

Title: Active Control of Thermoacoustic Systems
Abstract: Thermoacoustic instability is a physical process that takes place frequently in combustion systems, from aero-engines to land-based gas turbines. Thermoacoustic instability in combustors mainly results from interactions between unsteady heat release and acoustic field within a closed combustion chamber. In this talk, I shall present our recent study on the active control of unstable thermoacoustic systems, using Rijke tube, a classical, time-honored experimental platform in simulating thermoacoustic processes. For this system, we developed a first-order hyperbolic partial differential equation (PDE) model for one-dimensional compressible gas dynamics, combined with the Heckl heat release model, to describe the unstable thermoacoustic system in the tube. Two boundary feedback control strategies, including a boundary proportional control and a backstepping control with tunable parameters, are developed to achieve dual purposes: To decouple the interaction between the unsteady heat release and the acoustic field, and to stabilize the unstable thermoacoustic process. Interestingly, based on the Galerkin method, it is found that the thermoacoustic system in the Rijke tube constitutes an uncertain nonlinear high-order fully actuated system, which can be stabilized by employing feedback design approaches for fully actuated systems.

Title: Modeling and Control of Collision-Resilient Tensegrity Aerial Robots
Abstract: Adaptive UAVs have been widely applied in various fields due to their high maneuverability and flexibility. However, when facing tasks with multiple constraints and limitations, such as post-disaster emergency rescue and exploration in high-risk areas, UAVs reveal shortcomings in terms of safety and operational range. In response to the demands for deformability, impact resistance, and cross-domain operations posed by such special tasks, this talk introduces a new class of collision-resilient tensegrity aerial robots. First, we discuss six-bar tensegrity robots, including their dynamic modeling and control methods. By employing the port-Hamiltonian framework, the challenge of modeling intricate environmental interactions is overcome. Based on the developed model, we present closed-form analytical control laws using the form-finding approach. Furthermore, as an extension of pure tensegrity robots, we introduce modeling and control methods tailored for tensegrity aerial robots, which demonstrate nonholonomic and underactuated attributes.
