A Critique of Observers used in the Context of Feedback Control
Abstract One of the core tenets of feedback control is that a system's state contains all of the information necessary to predict a system's future response given future inputs. If the state is not directly measured then it can be estimated using a suitably designed observer. This is a powerful idea with widespread consequences. This paper will present a critique of the use of observers in feedback control. Benefits and drawbacks will be highlighted including fundamental design limitations. The analysis will be illustrated by several real world examples including robots executing a repetitive task, relay autotuning in the presence of broadband disturbances, power line signalling in AC microgrid power systems, Type 1 diabetes management and harmonic suppression in power electronics.

How Innovation of Autonomous Systems will drive the future
Abstract During the last 15 years, we have seen significant progress in many areas related to sensing, navigation, control and machine learning. Fundamental research contributions in these areas have enabled the development and deployment of autonomous system. Australia has been leading the effort in the field robotics area with the very impressive deployment of large scale automation in areas such as Stevedoring, Mining and Agriculture. This presentation will present a summary of the industrial outcomes of the Australian Centre for Field Robotics, current projects in the intelligent transport system area and an overview of the fundamental research challenges and opportunities in autonomous systems, systems having a continuous-time delay that is a fraction of the sample period will also be described. The talk will be illustrated by a real world example arising in Power Electronics where fractional delays arise due to both practical limitations of the gate driving circuitry and timing restrictions associated with the transition between switching states, otherwise known as dead-time. The importance of accounting for delays in this context will be exemplified by showing the impact of delays on the performance of high fidelity control laws aimed at selective harmonic suppression.

Micro and Nano-robotic Bio-cell Manipulation-- toward realization of artificial bionic systems
Abstract The micro and nano robotics technology has been studied for last two decades and has been applied for many sectors, such as industrial and academic applications. The modern industrial products can have many advantages of accuracy, efficiency as well as low cost productions, while the academic areas have many cutting edges technology applications to advance research fields, such as nano-materials, nano-devices such as sensor and actuator, bio medical applications and life sciences. Based on the research works on the 3D manipulation and assembly of the nano materials such as Carbon nanotube (CNT) and graphene, and bio-cell characterization by nano robotic manipulation, 3D cell bio-assembly research is to be presented, such that bio cells as assembled by micro and nano-robotic manipulation systems to form patterns and make various 3D structures. These bio-assembler by robotic technology is a very important tool for the bio-nano cell surgery, tissue engineering and Cyborg/bionic systems. Some of the examples will be shown in this presentation.

Large Scale Dynamics in Multi-Agent Systems
Abstract Large groups of high order multi-agent systems, including examples of vehicles platoons, can exhibit complex dynamics, including 'string instabilities'. The underlying causes of these dynamics, ways of ameliorating undesirable large scale effects, and underlying theory will be reviewed in the talk. We will also discuss the influence of various errors, disturbances and the possible effects of malicious agents in such systems.
