Nonlinear controller design from Plant data
In this thesis, data-based controller design methods for nonlinear process systems are developed. In the Just-in-Time learning (JITL) modeling framework, which is capable of modeling the dynamic systems with a range of operating regimes, four adaptive control strategies are proposed. These …

Multivariable controller design using pareto front
… The system is fully interactive so two different controller structures can be used to ensure that the temperatures track their respective set-points. Both are multivariable controllers though one has a diagonal structure while the other has a triangular structure. Multi-objective optimization with …

Fixed order controller design via linear programming
<p>Fixed order controllers, such as PD, PI and PID controllers, are the most commonly used in hardware implementations. Therefore, control engineers are often given the task to design fixed order controllers with time domain specifications as the system design requirements. To solve this problem, a …

Sliding Mode Controller Design for ABS System
… stability are to be maintained. While the design, construction, and location features severely limit the heat dissipation function of the friction brake, electromagnetic brakes work in a relatively cool condition and avoid problems that friction brakes face by using a totally different …

A controller design procedure for nonlinear stochastic systems
An improved method for designing controllers for nonlinear stochastic systems is developed and analyzed. The resulting controller consists of a nonlinear control law coupled with an adaptive state estimator. The nonlinear control law is developed first. Using Taylor series expansion, linear …

Controller design for underwater vehicle systems with communication constraints
Real-time cooperation between autonomous vehicles can enable time-critical missions such as tracking and pursuit of a dynamic target or environmental feature, but relies on wireless communications. Underwater communication is almost exclusively accomplished through acoustics, which bring challenges …

Controller Design for a Swirl Injection Hybrid Launch Vehicle
<p>This research is focused on the design of controllers for stabilizing a launch vehicle with an internally originating torque. The motivation for this research arises from the new development of rocket engines which swirl combustion gases to gain combustion stability benefits, and in the case of …

Decentralized state-space controller design of a large PHWR
… large scale system, a 72nd-order model, it makes controller design challenging. Therefore, a reduced order model is much more manageable. A convenient method of model reduction while maintaining the important dynamics characteristics of the process can be done by decoupling. Also, due to the …

Brachiating power line inspection robot: controller design and implementation
… Kalman Filter state estimator was designed and implemented to determine the full system state. Instrumentation used for measurement consisted of 2 Inertial Measurement Units (IMUs). The advantages of utilising IMUs is that they are less susceptible to drift, have no moving parts and …

Feedback Controller Design For Low-Power Autonomous Blimp Robot
… robots, and thus, their motion planning must be designed to minimize power usage. In order to test motion planning algorithms, a low-power autonomous blimp robot that uses buoyancy to reduce power requirements for three-dimensional movement was designed. The blimp has two forward-facing rotors …

Controller design for underwater vehicle systems with communication constraints
Real-time cooperation between autonomous vehicles can enable time-critical missions such as tracking and pursuit of a dynamic target or environmental feature, but relies on wireless communications. Underwater, communication over distances beyond about one hundred meters is almost exclusively …

A unified approach to structure and controller design optimizations
A unified approach to structure and controller design optimization is examined. Difficult problems arise in a unified approach, namely, a high dimensioned design space, nonlinearity, complexity of constraints and many inequality constraints. As a candidate for overcoming the above problems, an …
