This research work demonstrates a method to design adaptive controller for a class of nonlinearly parameterized systems with unknown parameters. The main motivation behind this work is to deal with the widely known issues with adaptive control systems like oscillatory transient response, sluggish performance and poor parameter convergence. Multiple identification models with second level adaptation...
Multiway PCA and multiblock multiway PLS have significantly enhanced process monitoring of batch processes by providing expected trajectory profiles for process variables along the batch duration. However, continuous processes lack of an equivalent technology because of their flexible operations and undefined time duration. This work presents a novel methodology to define operating regions where continuous...
E-commerce has gained a wider popularity among consumers during 20th century and is one of the fastest growing segments of Internet today. However, due to openness of information on internet, security becomes an important issue. One of the solutions to this problem is digital watermarking. Multiple watermarking is an advanced digital watermarking which provides increased security and robustness as...
This paper presents an effective switching state algorithm for flux and torque ripple minimization in direct torque control (DTC) of three phase induction motor drives. Proposed switching state algorithm gives an optimum flux and torque ripple at steady state condition and fast dynamic torque response. This control strategy is applied to three-level configuration using cascaded two two-level inverters...
In this paper, a direct load angle (DLA) control method for three phase induction motor drives is proposed. It is based on control of incremental change in load angle. This method offers constant switching frequency at different operating conditions. The torque control is achieved without losing the benefits of direct torque control (DTC) by reference stator flux angle, which is sum of load angle...
