This paper presents an evolution algorithm as a powerful optimisation technique for tuning Model Based Predictive Control (MBPC) at the implications of different levels of model uncertainties. Although Standard Genetic Algorithms (SGAs) are proven to successfully tune and optimise MBPC parameters when no model mismatch. SGAs are trapped in a local optimum at the price of model uncertainty. The multi-objective evaluation algorithms are capable to incorporate many objective functions that can meet simultaneously robust control design objective functions. These promising techniques are successfully implemented to stabilised MBPC at high model uncertainty.

In this paper, a brushless DC (BLDC) motor control system is implemented to apply to an x-by-wire system based on ISO 26262 which is a functional safety standard for road vehicle. Recently, conventional mechanical and hydraulic systems are replaced by electric/electronic (E/E) systems to enhance the vehicle driving performance and safety. Particularly, because x-by-wire systems have the safety-critical functions, the reliability of the systems is needed to be improved by considering functional safety. For hardware and software requirement considered functional safety, electronic control unit (ECU) of the proposed BLDC motor control system has a microcontroller with an asymmetric dual-core architecture and an external watchdog. Functional safety oriented monitoring functions are implemented by using the ECU design and also verified by using hardware-in-the-loop simulation (HILS). The proposed system is very effective for detecting the software faults and mitigating the influence of the hardware failures with the functional safety compliant ECU.

This paper presents a geometric method for solving the inverse and forward kinematics of Delta robot, and then investigated the problem of path tracking control. The forward kinematics is most commonly solved by various iterative methods, which may suffer from slow convergence rate and strict initial value conditions. In this paper, this problem is simplified as solving the intersection point of two circles and then transforming the coordinates system to get the final solution. This method has advantages in its simplicity, accuracy and efficiency. Based on the solution to kinematics and the derivation of Jacobian matrix, the path tracking control is studied from two parts: the superior trajectory planning and the lower control system. Trajectory planning aims to define a temporal motion law along a given geometric path. A method for trajectory planning is presented which is based on a modified trapezoidal velocity profile (TVP) of which initial and final velocities could be nonzero depending on its movement model, whether continuous path (CP) or point to point (PTP). A velocity control method is proposed using a nonlinear PD controller to ensure the end effector tracking the desired path with high precision. At last, a demo trajectory is generated to verify the feasibility of the method experimentally.

A Elevator system composed of a permanent magnet linear synchronous motor (PMLSM) as a stator and a magnetic plate as a mover is proposed in this paper. Rather than using a conventional encoder or resolver, position is measured by adopting a vector control method using two Hall sensors for generating a rectangular wave signal. This method estimates the velocity and position of a mover using the quadrature of two hall sensor signals instead of an encoder signal. Vector control of the PMLSM using two Hall sensors for generating a rectangular wave is proved to control the system in a stable and efficient manner through simulations. Hardware experiments reveal that the position control performance is within the range of 30~50μm with an accuracy of 10~20μm, a two-fold improvement over the conventional method. The proposed method exhibits an economical efficiency and practical usefulness. The vector control technique using two Hall sensors can be installed in a narrow place. Accordingly, the proposed method can be implemented in applications where conventional encoders or resolvers cannot operate.

This paper studies the problem of designing an observer-based admissible controller for singular delta operator systems. Sufficient conditions are provided for the existence of an asymptotical and physically realizable observer. Then an observer-based admissible controller is obtained in terms of strict linear matrix inequalities. The corresponding gain matrices appeared in our proposed approach can be constructed through the feasible solutions of a set of linear matrix inequalities. Some numerical examples are presented to demonstrate the theoretical outcomes of the paper.

This study developed a lower extremity exoskeleton system to enhance lower body strength. In this paper, selected the degrees of freedom (DOF) which actuated based on analyzed human motion, and analyzed the human joint function to design the joint modules of the exoskeletal robot. To improve the efficiency of the exoskeleton robot, a mechanical structure was designed on the basis of a semi-anthropomorphic architecture. The Hanyang EXskeleton Assistive Robot (HEXAR) has seven degrees of freedom per leg, two of which are powered by an electrical motor. Appropriately sized motors and gearing are selected, and put through a thorough power analysis. quasi-passive mechanisms were designed with compliance material for supporting the weight of external loads in the stance phase and absorbing/releasing the energy. This paper discusses design criteria considered in mechanical design for HEXAR.

On remote operation of a robot, it is important to provide the situation around the robot for the operator intelligibly and quickly. This paper presents an online 3D environment map construction by using a robot operated remotely. The environment data is acquired with only a stereo camera mounted on the robot. The 3D environment map is constructed incrementally from the data by online processing. Specifically, the map is provided by polygon-meshes with color, which are generated from environment point clouds. As for online construction of the map, the system has to execute divided process modules in parallel, in order to decentralize processing loads. This paper explains the system architecture to execute the process modules in parallel, and the details of the hardware in which the constructed system is implemented. Implementation of the system to a small mobile robot is also described. Feasibility of our system will be discussed on experimental results of 3D map construction in an imitated environment.

Identifying the mechanism for and predicting the metabolic shift between lipid accumulation and cell growth is a key research issue for microalgal biodiesel production. In this study, we propose a novel way to integrate a metabolic network model with a semi-empirical model (called “Droop model”) for predicting the lipid accumulation and cell growth simultaneously. At each time instant of mass balance model integration, the Droop model is used to predict the cell growth rate. Then, the Flux Balance Analysis (FBA) model is used to predict the rate of lipid accumulation, which is biochemically consistent with the predicted growth rate. In order to test the validity of the proposed approach, experiments are conducted for growing microalgae specie C. reinhardtii in a batch photo-bioreactor. Droop model's parameters are estimated using the gathered data and model predictions for the lipid contents are verified. Parameter sensitivity analysis is conducted to investigate how the various parameters affect the cell growth and lipid accumulation.

Recently, cyber security becomes a serious problem for not only OA (Office Automation) systems but also PA (Process Automation) and FA (Factory Automation) systems. Even the controllers, which are not connected to Internet directly, have been attacked with malwares, such as Stuxnet and Quantum. When control system fails, it may lead to serious accidents such as explosion or leakage of poisonous and deleterious substances. For process control, cyber-attack is one of the causes to threaten safety. The authors of this paper had proposed zone division of process control networks to ensure cyber security and safety. To apply the method, it is necessary to build CE (Cause Effect) matrices which express the qualitative information of the plant and controllers. It is very troublesome for large-scale plants. CAD (Computer Aided Design) tool for zone dividing is proposed in this paper. CE matrices are generated by using DAE (Differential and Algebraic Equation) registered in equipment modules of plant CAD such as ASPEN or Pro II. The candidates of zone division of process control networks, which can assure the safety against concealment and remote operation by cyber attackers, can be proposed.

In this paper, we developed the library for the microcontroller platform Arduino to apply in Modbus SCADA systems. This library allows Arduino board to communicate with RS-485 and use Modbus protocol which transmits data via a redundant bus. Experiments are conducted to compare the stability of data communication between a regular bus and a redundant bus which is the developed library. The results show the developed library Arduino board is able to communicate with redundant buses and more resistant to faults than conventional buses.
