Shiping Ma, Xiaobo Zhang, Zhanxue Wang, Tianmu Jiang(Northwestern Polytechnical University, China) |
| In order to overcome the shortcomings of the traditional process-oriented aero-engine simulation software, an object-oriented simulation software platform was developed to model the specific components of the variable cycle engine. Three common variable cycle engines are set up in this paper. In this paper, intelligent optimization algorithm is adopted to adjust parameter optimization space for cycle parameters and non-design point components given the same design point. The performance of the proposed engine is optimized under the conditions of ground take-off point and high altitude cruising point. The optimization results show that the comprehensive performance of ACE is best. |

Chaos Suppression Occurred in Spur Gear Mechanism by Reset Control |
|
Masataka Iwai(Ryukuku University, Japan) |
| Mechatronics equipment are required to control the response of machines at high speed and with high accuracy. However, many machines include pinion stands, gear couplings, etc., and there are some roles in the transmission part. When the response of these machines is increased, chaos phenomenon occurs due to the backlash, which is an obstacle to high speed and high accuracy. In this study, we show the result that suppresses the chaos to the gear transmission system by applying the reset control by simulation. |

Adrian Ritz Mabuna Chong, Vince John Bilog Casangcapan, Febus Reidj G. Cruz(Mapua University, Philippines) |
| This study focuses on the design and programming of a Arduino-based BMS charger that incorporates Solar and AC inputs. The primary objectives of this study are to evaluate the charging performance of the charger, evaluate the discharge characteristics of the lithium-polymer battery, and assess the results of dual charging. Based on the results, the utilization of both AC and solar power inputs led to a 91.35% energy efficiency. In addition, it is advised to utilize an alternative energy source, such as a battery, to power the system. The device allows a large percentage of the community to employ a cost-effective alternative power source for occupational and residential use. |

The PIDmn Controller Tuning for Temperature and % RH Control in a Chamber Using Simulink Desktop Real-Time |
|
Nuengsatree Boonseng, Arjin Numsomran(King Mongkut's Institute of Technology Ladkrabang, Thailand), Vittaya Tipsuwanporn, Jutarut Chaoraingern(King Mongkut’s Institute of Technology Ladkrabang, Thailand) |
| This paper presents the development and implementation of a PIDmn controller tuning technique for temperature and relative humidity (% RH) control in a chamber using Simulink Desktop Real-Time. The tuning strategy takes into account the specific requirements of temperature and % RH control, such as fast response, a lower percent of overshoot, and steady-state accuracy.Simulink Desktop Real-Time is utilized for the real-time implementation of the control algorithm, providing a reliable and efficient platform for testing and validation. Experimental results demonstrate the effectiveness of the proposed methodology in achieving precise and stable temperature and % RH control. |

|
Hojin Lee(Chung-Ang University, Korea), Youngwoo Lee(Chonnam National University, Korea), Wonhee Kim(Chung-Ang University, Korea) |
| This study presents optimal LQR control with vertex reduced linear parameter varying (VRLPV) method for planar stages.
The proposed control method consists of the forces and torque modulation scheme, a LQR current feedback controller to guarantee the stability of tracking error dynamics.
We propose a vertex reduction to eliminate the duplicating computations, a vertex expansion technique to solve the influence of the convex interpolation parameters in the LPV system on the tracking error performance.
To be optimal, a state feedback controller with the LPV gain scheduling is determined by using LQR control method. |
