The Rolls-Royce Inverse Model (RRIM) controller is a nonlinear, model-based fuel control algorithm. This paper compares the model-based design procedures and resulting performance of RRIM control to those of Classical Gain Scheduled (CGS) control for a three-spool gas turbine. It was observed that similar performance levels can be achieved using the RRIM with a significant decrease in tuning effort and design time when compared to CGS control. The RRIM controller also showed improved performance for the case of transient control. The paper indicates how and why the RRIM controller is robust across the operating envelope and highlights the practical advantages it affords to the industrial designer.

The torque and flux ripple of traditional DTC control of PMSM is large, and due to the lack of adaptive control system, the change of the system parameters has a great impact on the steady and transient control performance of the motor speed. Based on the traditional DTC control algorithm, a parameter identification adaptive backstepping DTC control algorithm is proposed in this paper. Because the backstepping controller is used to replace PI controller and flux hysteresis controller, the steady-state and transient performance of the system is obviously improved. At the same time, a parameter identification adaptive controller is designed, which can effectively suppress the influence of parameter changes on the speed control performance. The simulation results verify the correctness and effectiveness of the control algorithm. The control algorithm can significantly improve the steady-state and transient performance of the system under the condition of parameter mutation.

Automation of process control in chemical plant is an inspiring application field of mechatronicengineering. In order to understand the complexity of the automation and its application requireknowledges of chemical engineering, mechatronic and other numerous interconnected studies.The background of this paper is an inherent problem of overheating due to lack of level controlsystem. The objective of this research is to control the dynamic process of desired level more tightlywhich is able to stabilize raw material supply into the chemical plant system.The chemical plant is operated within a wide range of feed compositions and flow rates whichmake the process control become difficult. This research uses modelling for efficiency reason andanalyzes the model by PID control algorithm along with its simulations by using Matlab.
