Basic L1 Adaptive Controller: A State of the Art Study

Maiti, Roshni; Das Sharma, Kaushik; Sarkar, Gautam

Pages: 25 –66

[This chapter briefly describes the phenomenon of basic L1 adaptive controller. The slow transient performance of conventional adaptive controller is eliminated in L1 adaptive controller by utilization of high adaptation gain. At the same time robustness is also guaranteed with the aid of a...

Hybrid L1 Adaptive Controller-II: Fuzzy Parallel Distributed Compensation Based Approach

Maiti, Roshni; Das Sharma, Kaushik; Sarkar, Gautam

Pages: 113 –159

[In this chapter, fuzzy PDC logic is augmented with fuzzy L1 adaptive controller to tackle nonlinearities along with uncertainties and disturbances. The nonlinear system is considered as the combination of linear consequence rule based fuzzy systems. For each linearized zone, fuzzy L1 adaptive...

Speed Control of Electrical Actuator

Maiti, Roshni; Das Sharma, Kaushik; Sarkar, Gautam

Pages: 163 –179

[In this chapter, the controllers are employed on an electrical actuator, viz., DC motor experimental setup to validate their effectiveness. The control objective is to track a desired speed trajectory and to nullify the sudden occurrence of load disturbance without retuning the controller....

Angular Position Control of Two Link Robot Manipulator

Maiti, Roshni; Das Sharma, Kaushik; Sarkar, Gautam

Pages: 181 –198

[In this chapter, the lbest HS-L1 adaptive controller and fuzzy PDC-L1 adaptive controller are evaluated on a two link robot manipulator (TLRM) experimental setup to control its two joint angles. TLRM epitomizes a MIMO nonlinear system with uncertainties and disturbances. The lbest HS-L1 adaptive...

Temperature Control of Air Heater System

Maiti, Roshni; Das Sharma, Kaushik; Sarkar, Gautam

Pages: 199 –220

[In this chapter, temperature control of a delay dependent, nonlinear air heater system is investigated. The results show that, the lbest HS-L1 adaptive controller tracks the reference temperature trajectory better than the basic L1 adaptive controller. The fuzzy PDC-L1 adaptive controller...
