Title of Presentation: Intelligent Feedback Control for Operation of Complex Industrial Processes

Abstract: Process control should aim at not only ensuring controlled variables to best follow their set points, but also requiring the optimal control for the operation of the whole plant to make the operational indices (e.g. quality, efficiency and consumptions during the production phase) into their targeted ranges. It also requires that operational indices for quality and efficiency should be enhanced as high as possible, whilst the indices related to consumptions are kept at their lowest possible level. Based upon a survey on the existing operational optimization and control methodologies, this talk presents a data-driven hybrid intelligent feedback control for operation of complex industrial processes and a hybrid simulation system. Simulations and industrial applications to a roasting process for the hematite ore mineral processing industry are used to demonstrate the effectiveness of the proposed method. Issues for future research on the optimal operational control for complex industrial processes are outlined in the final section.

Title of Presentation: Miniature Mobile Robots Down to Micron Scale

Abstract: Miniature mobile robots have the unique capability of accessing to small spaces and scales directly. Due to their small size and small-scale physics and dynamics, they could be agile and portable, and could be inexpensive and in large numbers if they are mass-produced. Miniature robots would have high impact applications in health-care, bioengineering, mobile sensor networks, desktop micromanufacturing, and inspection. In this talk, dynamics and control of different size scale miniature robots with various locomotion capabilities are presented. First, as milli/centimeter scale mobile robots, mechanics, design, and control of climbing, flying, and water-walking robots inspired by insects and lizards are presented. Pill-size untethered soft capsule robots are proposed to enable minimally invasive medical diagnosis and therapeutic operations inside stomach. Next, going down to sub-millimeter size mobile robots, the grand challenge is the limitations on scaling down on-board actuators and power sources. Two alternative approaches are proposed to solve this challenge. First, biological cells, e.g. bacteria, attached to the surface of a micro-robot are used as on-board micro-actuators using the chemical energy. Current status of this approach is reported briefly while focusing on a second approach: external actuation of untethered magnetic micro-robots using remote magnetic fields in enclosed spaces. New magnetic micro-robot locomotion principles based on rotational stick-slip, spinning, and rolling dynamics are proposed. Vision-based control schemes are used to control teams of micro-robots using novel addressing methods where each robot in the team could be individually actuated while the global magnetic fields exerted on each robot is the same. Such untethered micro-robot teams are demonstrated to control microfluidic flow locally, trap live cells and transport them, and manipulate micro-gels with embedded cells with or without contact inside microfluidic channels for tissue engineering applications.

Title of Presentation: Multiphase Drives: Power Electronic Supply Control and EV Charging Options

Abstract: Multiphase (more than three phases) machines are characterised with a number of favourable features that make them an excellent candidate for a range of applications, such as electric vehicles, locomotive traction, electric ship propulsion, ‘more-electric’ aircraft, and various high-power industrial processes.
At the heart of any variable-speed multiphase drive or generation system is a multiphase power electronic converter. The first part of the presentation will therefore concentrate on recent advances in the area of multilevel multiphase inverter PWM control. Two topologies will be addressed, a three-level supply in single-sided supply mode and dual two-level inverter supply with open-end stator winding configuration. Some of the recently developed carrier-based and space vector based PWM techniques will be surveyed and the achievable performance illustrated using experimental laboratory prototypes.
Multiphase machines are characterised with existence of additional degrees of freedom, since only two independently controllable currents are required for flux and torque control. In very recent times it has been shown that one of the potential uses of these additional degrees of freedom is for realisation of integrated on-board battery chargers for electric vehicles. For this purpose the machine is brought into an open-end stator winding configuration, so that this established the link with the first topic of the presentation. The second part of the talk will therefore address topologies and control of multiphase converter/propulsion motor powertrains, in relation to charging and vehicle-to-grid (V2G) operation. The emphasis will be placed on the nine-phase topology, which appears as the best candidate for future EVs, since exactly the same system suffices for both propulsion and charging/V2G modes of operation. Experimental results will again be included to validate the theoretical concepts.
